Supermarkets.
They are just places where hope goes to die.
I usually go to Asda and there are almost never any trolleys at the door so you have to walk back to a trolley bay in the car park to get one. Said trolley is always filthy (remember during COVID when supermarkets actually cleaned trolleys and baskets for a few months). The stores themselves are always a bit grotty looking as well. You start at the fruit and veg which is always really sad looking. Going around it seems the main aim is pushing people towards buying high margin junk food with said items dominating prominent positions and always with deals trying to push you towards it. Stock availability seems increasingly crap (as an example last night Asda had no fresh carrots. Not loose, not the cheap bags, not the bigger bags and not the expensive organic ones, literally not a single fresh carrot to be had). You have a choice of scanning as you go or self scanning at the checkout, if you are lucky you might get 1 or 2 checkouts open but employing actual humans seems an inconvenience for most stores. You come out and when going to return your trolley inevitably the first 2 or 3 bays you go to will be rammed full because employing enough people to collect them in good time means slightly lower profits and most people are decent enough to keep going until they find a bay they can squeeze their trolley in so they don't bother.
The worst part is I know there is a choice. I can take a bit longer and spend a bit more and shop in nice local shops with real people, local food and higher quality but I choose convenience and that's why they get away with it.
