Heck I used to love em, guaranteed extra time and money. When I just started out, a tiny outfit in Spokamentro, we'd get 'a call' late Friday afternoon. It would ALWAYS be "some bar" we'd never heard of. They of course had no credit and had tried to stiff some of the bigger outfits, so they tried yellow pages roulette.
You ALWAYS wanted to nail 'em down on the phone, and tell them 'we want xxxx deposit up front.' A couple of times or more were wasted trips. You'd go out there and suddenly the boss "was gone." Well guess what? So was I LMAO.
N' yah, we got stiffed once, for a compressor. One afternoon my boss looked at me, and said, "Why don't you go up there and throw that compressor right off that roof?" (Meaning pull out a brand new compressor we had not collected for)
