My gosh. It is just a small amount for you to audit and have an account for that for 1,000.00 customers as you have mentioned as profit. Of course not. It is profit if you do not receive your change, but they are offering you an alternative, chewing gum for instance which in itself entails cost.

As our QL members here mentioned, they do not mind for these small things, and I myself would mind some other bigger and worthy things.

Live and let live.
