It should be illegal to charge non customers a fee to cash a check that is drawn from that institute. This is just another example of banks trying to administer fees any way possible to make a buck. How is it different if a non customer deposits that same check at their own bank. The bank the check is drawn from still has to process it, so either way, it part of a normal transaction.
