i've only had 1 customer that bounced a check. the bank charged me $3 so i didn't worry about it. the customer just wrote me another check. i just ate the $3 charge. i guess i could've just told them to make the check out for $3 more but it wasn't a big deal. that is the only time that happened. all of their other checks never bounced. i just figure they made a mistake. it happens.
