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.
I mean, I’d argue that “Thank you” always implies acknowledging a social debt; if you don’t feel there was a social debt someone just assisted you with, I probably wouldn’t say, “Thank you.”
“Have a good day” would just as equally and politely close the interaction while not implying you were just assisted with a social debt.
I agree and I use that all the time.
Even if “thank you” acknowledges a social debt then you’re not indebting the cashier by thanking them. Being told you’re welcome implies that you owed the cashier when they simply did their job.
Anyway, apparently I’m in the minority on this and that’s fine!
