Let's say my good friend Bob is an employee at Frank's Store of Stuff You'd Never Pay Full Price For. He gets an employee discount for his purchases there. Can Bob buy stuff and then sell it to me, or buy stuff directly for me?
What about for his wife and immediate family?
Let's say that the owner is unavailable to ask if he is OK with that or not, and my one-way flight to Mars is about to leave so I can't wait until he becomes available.
