Water usage is probably my biggest. Living in a high desert, my wife and MIL see no problem with filling one side of the sink with hot soapy water to wash a few dishes because “that’s just how I’ve always done it”, to watering the grass and plants for hours. All of this makes me mental.
Similarly, I find it slightly annoying when you thank a cashier and they respond by saying you’re welcome. This exchange was purely transactional (I paid for my items and you did your job), so please don’t imply that you did me some sort of personal favor. But like you, I won’t say anything about it to the cashier because their job is already hard enough.
I don’t get this one. You started it going with the thank you. now they have to say your welcome.
When you thank a cashier, it’s just the standard polite way to close the interaction and you’re not actually expressing gratitude to them for simply doing their job. Responding with “you’re welcome” overstates that transactional exchange and implies a social debt that doesn’t exist. It’s an exaggerated response that comes across as presumptuous.
BUT that’s not their intent, they’re just mindlessly saying “you’re welcome” because that’s how their manager or grandma or someone taught them to respond. So although I find it mildly annoying, it’s not something I’d ever point out to them.
