In Which I Could Have Worked for Nissan

Me: Hi, I'd like to apply this discount to a new Sprint plan.
Radio Shack guy: OK... Hmm. It's not showing up for as much as it should. But I can just give you a different discount.
Me: What do you mean?
Radio Shack guy: I'll just say you work at Nissan and give you their employee discount.
[Note: I do not work for Nissan.]
Me: Umm. I don't feel comfortable with that.
Radio Shack guy: Well, I don't know what to tell you. It's up to you to do the right thing.

I did not get the new phone plan, which means I am still currently on a cell phone plan with virtually no service, but, um, isn't it up to the Radio Shack guy to do the right thing, too?
