I have a guy who owes me a little over $200 for mowing. He wrote me a bad check, won't return my phone calls, and has not responded to several letters, including one sent via certified mail. I know this is a small amount, but on matter of principle, I hate to let him get away with it. Do you think its worth filing in small claims court or using a collections agency, or since its such a small amount, should I just write it off and move on. Your opinions.
