Hard times for a local Contractor

That happened to me years ago, but not on a commercial account, and not to anywhere near that amount ($600). Bank covered my loses. Only problem was, they knew who did it, but the bank wouldn't peruse it, and I could not press charges because I didn't suffer a loss (since the bank covered my loses).

Banks are not being very careful about looking at signatures on checks. The last incident I was involved with the checkbook was stole in a brief case with other documents. The person who lost the brief case was more concerned about the insurance papers lost, and forgot the check book of the none profit group was in the case.  So they had 48 hours before anyone was looking. But no attempt was made forge the correct signature. They just put John Henry, or something on the checks it at big box stores. Since one small purchase worked the next day they went $1000 worth. It was being processed when the alert was sent out, so did not clear.
