If you don't mind hard work and can resign yourself to small paychecks, PT work at UPS is pretty great really. I don't have to deal with customers, put on a fake smile and be pretend nice, don't have to kiss anyone's ass, including management, can show up wearing tattered rags, only have to shave if I feel like it, and basically get a workout while BS'ing with a great mix of personalities.
Of course there are days when it's a real grind, but even then it only lasts 4-5 hours.
