I usually say....never mind...I'll call corporate....and boy does that move walls.
Yep. I had a issue at Home Depot with a cashier refusing to do a tax-exempt purchase, saying they I did one just a week ago. I showed them the company credit card, and even though the internal tax-id number matched the card, they refused to click “ok” to remove the sales tax. I pointed to the posted policy on the register, that I followed exactly.
I ask for a manager, they said they were the cashier/front end supervisor. I asked for the MOD for the store, they said they wouldn’t call them. I ask for their name, told them I would call corporate and walked out.
The Store Manager called me a day later, asked some questions, what time, register, items I wanted to buy, etc. A few days later the District Manager called, said to go to the store as ask for the MOD. They had a box with all the items I was going to purchase, about $80 worth handed me that and a $50 gift card and said I was all set.
Never had a problem with that cashier again.
