I got the hot check line too,
There is no problem getting the attention of a bad check writer...take the bad check to the cops and they will arrest the writer. My only problem with bad checks over more than fifteen years was checks the girls in a fulfillment office lost. The customer wouldn't write a second check...I said I mailed it in..they said they never got it......and that was a "refundable deposit" from the ProSat turkeys years ago.
The custom work was the only reason to consider doing installs for 50 & 15. The custom work had to be profitable because you would loose money on that rate.
Grrrr!
