It really sucks when you get stiffed from a customer. I had 2 instances in 4 years. One was a guy who rented and moved. He said "send me the bill" and disapeared. The other was a condo. association who later paid (six months later) because I took them to small claims court. I could say that I lost $130.00 from the first guy, but all I really lost was $5.00 worth of gas and 1.5 hrs of my time.
