Cashiers here have started saying "have a good rest of your day" instead of "have a good afternoon" or something.
It never used to be a phrase.
Its very common now.
I understand that language evolves and that this is probably used often enough to be dramatically "appropriate" now, but i just hate it.
Some how the grammar is just discordant and I find it jarring every time.
Of course, I dont tell cashiers about this grievance, because I appreciate them and I understand this is just me being weird and I try to get through my day offending the fewest service workers as possible.
