Replying to What is the worst job you have ever had?

I worked at a hotel last summer as a housekeeper (aka a maid) to pay for some new gear. I had to listen to some foreign lady yell at me all day for not getting all the pubic hairs off the bathroom floor. The hours sucked (I worked 6 12's), it was humiliating, and exhausting. Needless to say it was one of the longest 3 1/2 weeks of my life.

What is the worst job you have had, and what did you learn from it?
