I really, really hate supermarkets. I think they're like a little microcosm of everything that's bad about humankind. Like when people put their trolley away in the trolley bay; do they slide it into the previous trolley and leave every neat for the next person to come along? No, they throw the trolley in any which way. After several of these, everything gets tangled and it screws everyone else up (I'll tidy them up when I take mine back as I hate to see the mess). Then there are the people who treat it like a social event and stand around in groups, chatting and blocking the aisles. The cashiers who pass everything through the scanner as fast as possible without caring if you can keep up with bagging your food. People dawdling and browsing - why! a***holes who take the disabled parking spaces (which I need for my wife) for their crappy 4w-drive monsters and force me to drive around and around until one becomes free. People who seem to forget that they need to pay for things and spend 10 minutes searching for their purse/wallet. People leaving their trolleys, unattended, in the middle of the aisle while they disappear to get something. The noise, the tannoy, the lights, the way they move the stock around every few weeks to mess with my Ch'i. Argh!
I always take a list (I have a planned menu for the week on a whiteboard at home). I know the prices because I generally buy the same things each week and quickly scan offers to see if something is cheaper. I put everything in my trolley in order and I then put the shopping on the conveyor in order so I can bag things correctly (yes, I am that anal) - that is if the cashier doesn't act like a dick and scan things out of sequence on purpose (the other day I had cartons of orange juice lined up in front, behind those some bottles of cider and behind those a box of wine. The cashier scanned them in this order: oj, cider, oj, wine, cider, oj - she actually reached behind things to mess with me!). I then leave as fast as possible. I can get a week's worth of shopping for a family of four in 10 minutes if there's no queue at the checkout.
Supermarkets are full of laziness, inconsideration and I hate them. Rant over
