Assuming they don't know what the FSF is, they'll just think it's the business you work for, and will follow standard procedure. If they do know, they probably won't pay it much mind, or not enough for it to matter.
I don't know why you'd want to troll anybody who works retail. They are just grunts for the company, they have no say in policy or decision making. Some of these guys might not even be Apple fans specifically, they just took what they could.
