I can see your point but I would much rather see someone at least try to pretend they are enjoying themselves. If you don't like the job, don't take it. It's that simple. It doesn't serve any purpose to accept work and intentionally make things miserable. It wastes everyone's time and my money.

People would much rather see happy performers, I think. I know it's tough but there are much tougher, lower paying jobs out there.
