congrats!
but if something like this occurs again (to you or another PFer), I think it's perfectly fine to buy things under the table. To be safe, you can always ask for a "contract" stating bagX is bought with Y amount of money and then both of you should sign it. Now there's no way for the SA to run away with your money cuz you can always go back to the store and tell his manager of what he's doing illegally and make him lose his job lol
