Any question answered...

Tut quietly.

No good could ever come from confronting them and plenty of bad might.

Doing nothing is very frustrating, but it's the only way I think ..

Oh I love this idea:)

My mum would have gone over and tidied up the rubbish.

Yes I was considering this, just start picking it up in front of them

Hammer some frozen sausages into their anuses after you dragged them out their car and tied them up and ball-gagged them over a tree stump.

Private car park?
Get the reg number and snitch to the owners?

Treat the situation as a recipe: return ingredients to original container, beat contents vigorously with wrecking bar, leave to marinade.

I've got some venison tenderloin that I've just defrosted with a view to making a mean Wellington.

Can I substitute mushrooms, which are fucking rank, with something like a spinach and lentil mix?

Kind-of a MacGyver approach, I like it 👍

Substitute the venison for more mushrooms.

Mushrooms are the work of the devil

All of them?

I've enjoyed liberty caps occasionally. Not the actual consumption

Would spinach and lentils be a decent substitute? I've never cooked with mushrooms.

My tenderloin is looking at me longingly

I'm longingly looking at my tender loins.

All of them?

Mostly just Devil's Dispstick and Devil's Fingers

Would spinach and lentils be a decent substitute?

Which recipe are you following? If you're preparing duxelles, I don't think a lot of harm [apart from wrecking the flavour] would come from leaving out the dried mushrooms and not adding anything in as a substitute.

I don't think I'd be averse to sweet red peppers instead of fresh mushrooms if you think the water content needs to balance.

What's the name for that really sticky double sided tape?

It's a few mm thick and I believe produced by 3M.

Do you mean Command Strips? I believe that is the consumer targeted, removable version. 3M sell dozens of different double sided tapes depending on the application.

really sticky

The technical term is VHB (very high bond)

If I buy a pair of black jeans and wear / wash it oftentimes, will I then have a cool worn-in grey jeans, or rather a pretty dull "washed out black" jeans?

The latter. But live the thrill of a jet black pair until the first wash.

Which could be 6 months wear….

You could ask in the selvedge thread, but it depends a lot on what colour the weft is and how/when you wash them.
