The trick I use is: I am here to exchange time for money. Whatever happens during that time, I really don’t care. The company tells me what to do during those hours and I do it to the best of my ability. Someone complains at me? I don’t care. Someone makes me do extra work? I don’t care. Someone’s having fun behind the trash compactor for the fourth time this month? I don’t care. A customer attacks me because we’re out of a particular single beer can, even though we have it in different sizes and multipacks? …ok, that one was fucking hilarious in retrospect and I’ve dined out on that story for a decade.
