I'm thinking of a Miss Manners letter form unknown time ago, about the time it took to "get sorted" after paying. The LW had been sniped at for being too slow. While MM agree it was rude to snip she also told the LW an actual minute is too long do try to be faster. I think there is a gray area
using that letter as an example 5 minutes to sort your coupons , balance your checkbook and resort you credit cards is rude a minute to record a check , put cap on pen , put pen in pen section of purse , zip, put checkbook back in it's section, zip that section, put DL back in slot, zip wallet , snap wallet , put wallet in purse, zip purse is annoying not rude but it's still polite to try to not be annoying.
So I think am I being annoying /do I have any reason to be annoyed? does have a place here. I'd want to know if my not rude behavior was annoying 90% of the population, I also want to know if I'm annoying by something 90% of the population does/is not bothered by. Etiquette is always evolving today's annoying might become tomorrows rude.
