Why I hate working in the food industry

Ya, i came home from work in a really bad mood today, so I'm just going to list a few points:

• The people you work with always have to be cheery, including yourself. A lot of times I'm delightfully glum, so you can see how this annoys me. Don't get me wrong, I love seeing people happy, it's phonies I hate. Also, you don't know if your co-workers are being passive agressive or sincere. One thing I hate is insincere people.
• The floors are so fricken greasy and slippery!
• I come home smelling like milk, ew.
• People in the fryers go home smelling like grease, poor them.
• Customers sometimes can be so picky annoying.

I'd quit, but I just started, so I'm just going to put up with this for a bit. If by the beginning of next summer I still want to, I'll quit.
