I worked for a guy that did this too. Instead of me losing sleep over it, I put my job on the line (because if this was standard operating procedure then I would rather be unemployed...) and told him he needed to come clean with who he sold admitting he was at fault and not the developers/etc. If a sales person has to eat crow they quickly learn to avoid future crow eating. Things were much better after that.
