Is it rude or inconsiderate to disacknowledge well wishes?
For example, say I’m your cashier, and at the end of when I ring you up, you say “Have a Nice Rest of Your Day.?” Would it be considered rude or mean to just completely disregard or not even respond to you in anyway? What if I just were to walk away from you and ignored and showed no sign of interest? Would you think that would be rude or not normal to disregard or not acknowledge people who are just wishing you well?
