go hang out with the Mexicans that wait for temp work in the morning. (if you're in a country besides America it might be Poles, Libyans, Syrains, or Ukrainians). You'll get put to work doing the kind of shit that destroys your body. And Mexicans are pretty good coworkers generally.
Make sure you look sufficiently downtrodden. The bosses can smell a privileged weakling from miles away.
