Thank you all for your answers! I love how basically all of your favorite jobs are different in many ways :)
sfcowgirrl, thanks for asking - my favorite job was when I worked for a restaurant/hotel when I was in high school. I learned so much because I would have to fill in on so many aspects - waitress, dishwasher, cook, desk clerk, housekeeper... It was a great learning experience and something I will always remember. I loved the waitress aspect the most because I got to talk to so many people and would also get free food like cooldad would.
