Dear Jim, I can't fault you for the way you handled this transaction. Others have given their opinion and some are quite compelling, (i.e. 400 Nitro Express). However, it's your sale and you make the rules. I get ding-dongs in my shop from time to time that want me to do things for them that are not just above and beyond, but in freakin' lunar orbit. case in point, a guy comes in and said, I bought this stuff from you 2 years ago, I just cleaned out my garage, I want credit. Or, "I know you closed 1/2 hours ago, but you should wait on me, cause I tell my employees to wait on everybody, even if they are there until 2a.m. Point is, in business, you alone make the rules,you can't let people dictate to you what you policy is to. If you are under obligation from GB to abide by a certain definition of a 3-day return policy, then you must do it. If not, Your stance will keep the boneheads away.
