I'm very up in the air about whether or not to write a letter or go over his head. On one hand I say go ahead and contact corporate and make a complaint and take it all the way up so he gets a lesson in proper customer service as well as coupon usage. On the other hand I understand this being the only store you have and don't want to have to stop going there.

I don't know what to say, but I guess I'd say write the letter (shorten it A LOT) and send it to him as well as his district manager. But also try to fly under the radar for awhile ( I don't mean don't shop there I eman don't go in for 20+ transactions a day). Just go do what you need to with a plan in hand get in and get out.

If he EVER approaches you again about this you should take it a lot further. You don't need to be told you can't shop there cause he's jealous of your deals.
