Annoying customers

After having spent a few years in retail (not any more!) I have to take issue with this.
A customer has the responsibilty to be a decent fucking human being and not be rude, arrogant or condescending, all of which people in retail face daily. Say hello, get off the fucking phone, don't talk down to me like this is the only job I've ever had or am likely to have and for fucks sake open your eyes and look around. Yes, you are paying for goods/and or services but it does not give you the right to circumvent normal polite behaviour.

What conversation is there? Example I go in to Uniqlo for a cashmere cardigan (like rapha but better ;)) I go and pay cash little bag conveing for usually a no thanks. Thats it.

What am I paying for is the item. I await self service tills at more shops as they are cheaper than staff.

In a restaurant, bar I want to be served. Don't want fake conversation just my order taken. Don't want a comment unless there is none of that item or if this is not the best night to order it. I do not want commentry that I'm having something strange as its on the menu so I want it.

I to have worked in retail and behind bars too. Maybe fancy doing bar/food stuff again at events as that was a laugh.
