It was early on in my business and my business partner and I didn't really know what we were doing other than how to network and get contracts. Since we didn't really know what we were doing we sub contracted another company to do the work. One month they didn't pay their employees, even though we had paid the company the agreed upon subcontract rate. The employees refused to work unless they were paid so I paid them directly and they started working directly for us and then we went took the guy that owned the company we were subcontracting to to small claims court for 3500 (or something like that) which was the amount he didn't pay the workers and I had to pay out of pocket.

Anyways judgement was in our favour but we never saw a cent because the guy was broke and claimed bankruptcy on that business and then put a new business in his girlfriends name.

Live and learn.
