My neighbor come to shop at the store. He specifically called for me, as I don't stay at the front lines of retail but behind, doing other stuff, and jokingly asked, "can I get neighbor discount?". I said sure, and while he's in front of me, I call the supervisor at the phone to approve that. Not even ten seconds pass that he's shouting in my face "can you hurry with that price? I have something else to do!!".

I hung up the phone, sorry, you asked discount, I had to approve that, your price is $LIST_PRICE
