I hate thanking chik-fil-a employees.
Why do you not thank them?
Because I hate being told what to do
It doesn't make sense why you would be mad that you have to thanks someone for serving you. It is a common courtesy and there's no need to get mad.
It's fine if others do it, but I don't like being pressured by society to do it.
It's understandable to not like following rules that you feel are forced onto you. But these employees work hard to serve you for little pay. Just two words are enough to show them respect.
