A LOT of jobs require difficult things from their employees. I don't see smiling as that much of a chore, considering I clean up hemorrhages, shit, puke, piss, persuade people to take their medicine, help women change sanitary their sanitary napkins at times, change diapers ALL the time, start and manage IVs, get people through emotional and psychological breakdowns, some which include suicide threats, persuade women to feed their babies properly and TEACH them how (nearly always getting their milk all over myself in the process) see people in pain and have little resources, besides a pill and a kind word to help them, have to be ready to give CPR to a stranger at any minute, and and on my feet the entire time. And, that's usually only my first hour...
Smiling all day doesn't sound that bad. They wouldn't call it "work" if it was ALL fun.
