I hate

Surely satirical.

my partner has been collecting plastic containers from takeaways and pasta sauce pots for the last year so that she won't be upset when our daughter loses 'real tupperware' at school
After I blew my top at them having completely taken over a cupboard that was in high demand for the rest of its contents she agreed it had gotten out of control and moved them to what would be a dedicated cupboard.
Much to my dismay the collection has since quadrupled.
Worse still, finding a lid to correspond with a bottom is a laborious affair that sees the whole cupboards contents slipping out of it.

Long way to say I'm completely with you.

finding a lid to correspond with a bottom is a laborious affair

After the Nth time of desperately looking for something possibly stored behind the towers of tupperware in our cupboard, and breaking out the special non-English curse words for the frictionless shape-shifting hell spawn said tupperware becomes once disturbed, my partner agreed to keep only what we could store with their lids on. We may have fewer but we’re never without the lid, and they’re easier to re-stack when moved.

We have a nice neat stack of tubs and matching lids from the various curry places we order from, which also act as a wall to hold back the pulsating mass of mismatched clustertub Armageddon behind.

One thing I’m happy to see the back of is the carrier bag cupboard of yesteryear

Riffing from the tupperware matching - why the fuck are most sets of socks sold basically identical, just with slightly different colour toes/tops. Maddeningly, it's particularly impossible to avoid with kids socks sets.

Have the people selling kids socks ever met:
a) any children
b) any parent

Why on god's earth would you create a sock set so entirely reliant on finding the matching sock to complete the look you had hoped to achieve? Just sell a set of identical socks you stupid twats.

Just sell

Answered your own question there.

Say what you want about the downsides of military life, but I never once had to stress about mismatched socks.

Don’t kids generally prefer mismatched socks? Regardless, just buy multiple sets of the same pattern if you want to avoid that frustration.
Caveat! IANAP

Don’t kids generally prefer mismatched socks?

Depends on the kid. One my mine went through a phase of wearing day of the week socks and would have to wear the correct pair for the day. Easy to pair.

People who won’t pay before they’ve put all their groceries in their bags. Extremely slowly.

People who don’t put a divider behind their groceries.

Standing in line.

Why isn’t it the responsibility of the person putting their groceries down behind someone else?

same reason you clean the toilet pan after you use it.

The person in front knows when they're finished, the person behind may be at the other end of a trolley for a bit.

Coz the divider is usually further up the counter so out of reach for the newly arrived back-of-queuer

People

I got lambasted for bitching about people who don't bag their groceries until after they've paid and scanned at self service tills. I still stand by it. If you have your own bag, put that down first. Don't give me that "but the bagging area always fucks up if I do that". It probably happens 1 time out of 5. I can't even remember the last time it happened to me. Why would you want to pick something up twice. Sort your bag, scan, straight into bag. Unless you are using a backpack or something bigger that will fuck up the scales, I give a pass for that. But even then, it's a simple call to the attendant to reset the till. Don't make me stand there in line while your till is ready for the next customer but you're only now pulling your bag for life out of your pocket.

people who don't use the apps to bag their stuff during the shop

If available, god yes. Minimal interaction. The pain then is the "random accuracy check". And, to be fair, one time I did miss a pack of ice lollies and the whole trolley had to be re-scanned. And another time, I was using the app on my phone and it crapped out 3 times at check out so everything had to be scanned 4 times, luckily it was only a couple of bags. On the fourth, they just gave me the "queue buster" handheld scanner which effectively overrides any checks. I'd still use that system over a manual checkout.

I wonder if they have sensors to capture how long you spend in what part of the shop, or to record your path. 🤔

Some retailers do that by tracking WiFi beacons sent out by your phone - connecting to the WiFi network not needed. If you do connect and perhaps provide some details in the AUP click through then they can get some more detail about who is lingering but not purchasing in which department.

Impatient people

I'm not sure supermarkets bother with this sort of tracking - they already know who does what and where, as the result of time & motion studies, done old school analogue style, since forever.

I guess there may be an argument for micro-marketing based on individual / cohort movements, but my guess is not much, based on cost versus benefit.

No doubt marketing loves the idea, until analytics shoots it down with numbers.

Exactly.

All these whining boomers using checkouts in physical supermarkets need to take a moment and breathe.
