Going to Tesco will certainly help your newly developed grumpy old man persona.
Here's my ranking of how the local supermarkets make me even more grumpy (least stressful to most):
- Tesco. Nice wide aisles, plenty of well designed parking areas and staff that aren't openly obnoxious. Excellent variety and quality of fresh food. They even have that self-scanning thing that means I don't have to talk to anyone if I'm in a really foul mood.
- Closest Asda. Small, very friendly store with outstanding staff who go well out of their way to help including keeping checkouts open even when they're unused. Doesn't have many of the things we need though due to it being small and the customers are like those out of that "People of Walmart" site.
- Waitrose. A nice store, a bit small though. A mix of vastly overpriced brand-named fresh-food (e.g. that Duchy stuff that obviously gets hand-packed by Prince Chuck himself given how expensive it is) and some good bargains as well as stuff you can't get anywhere else. Must be avoided at 3pm and 7pm though as that's when they restock their "discounted" fridges and you get a swarm of people fighting for a bit of meat reduced to merely expensive instead of usurious. It really has to be seen to be believed, all these middle-class and aging women barging each other aside to get to the discounted stuff. Staff are friendly but not very useful.
- The big Sainsburys. Good supermarket, friendly staff and good produce. Abysmal parking though with nowhere near enough parking slots even during quieter times.
- The big Asda. Big store with everything we need. Unfortunately the place is like a warzone with grumpy staff, combative customers who don't understand basic civility and fresh food that lasts seconds when out of the store.
- Closest Sainsburys. Mid-sized, ratty, dirty looking building with poor parking and a few poorly timed sets of traffic lights leading to it. Far too much fresh food is off while on display every time we're there for it to be a one-off thing. Staff are OK though. Too close to a selection of local schools so almost 1/3 of the parking slots are parent and child, vastly outnumbering disabled slots and leaving normal slots at a premium.
edit: swapped the local Asda and Waitrose around as I'd put them in the wrong order.
