Has anyone else experienced this?

Shortly before Christmas, I was at the Home Depot over by Park Meadows, making a purchase. I pulled out my military ID, and was informed that they no longer give military discounts "except around the holidays." Nobody could tell me when this was enacted, or anything more specific than that.

The second week of January, I stopped in to see if it was a fluke, and the clerk gave me a military discount.

Yesterday, I stopped in and was informed again that there was no discount.

What the hell?
