Poor attitude

Was at the Gateway store yesterday (Thursday) and they had their Monday board out with the coffee special. Made my purchase and asked the cashier if they would honor the Monday deal, even though it was a Thursday, given that they were advertising it.

She had a long chat with her co-worker and I thought they were going to bring the board in. However, when I left, the board was still outside.

I asked, more than once, to speak to a manager and I was dismissed and my request was laughed at. No way to treat any customer.

This is less about the coffee (their error) and more about the attitude of the staff.
