Honesty

Does honesty pay off?  I do a lot of work for a large cabinet company in the Jacksonville area.  I noticed areas of my bill where they would trim dollars.  Kind of hurts since we have been cut a number of times already.   Anyway, I found a line item where they actually overpaid.  And I brought it to the attention of the guy who runs the bills.  His reaction was not "thank you", but "will look into it Monday."
