What job could you NOT do?

[cbloom]

Sales. I'd want to kill myself. That includes things like mortgage brokering where you make your money by ripping off hard working people.

Waitering. The first time a customer was an ass to me I'd spill his food in his lap or just never bring it.

Anything where you have pretend to be cheerful all day, like workers at Disney World or flight attendants or anything like that.
