When I worked fast food, I had a customer in drive thru with special orders. This was back when we kept the sandwiches all made up in the warming bin.
Before they started keeping the cooked patties and buns in heating trays and put them together after they ordered. If you wanted to hold the pickle back then, we had to try to catch it off the next batch on the grill or make it from scratch to order.
So of course I told him it would be a couple of minutes wait. He wouldn't stand for it. He wanted his money back so he could go to competitor. So we had to have him pull forward, while I ran back to the register at the first window, voided the order and got his change.
I ran it out to him and he complained that it wasn't enough. He thought that we were only refunding the price of the food and not returning the tax he paid. So I ran back in to get a copy of the receipt so he could see he got refunded exactly what he paid, tax and all.
When I ran back in, I was informed that the special orders were up. The grill didn't know they were cancelled. So he could have had them in the amount of time he had to waste any way. He didn't have time to wait 2 minutes, but he had time to wait 4 minutes to make sure he got the tax back too, 10 or 15 more minutes to drive to competitor and also wait another 2 minutes or more, because competitor also made special requests to order at that time.
When I worked at Hardees, we had two Hardees in our town. The other one delivered, we didn't. They delivered all over town though.
I answered the phone one day and the guy wanted to place a delivery order. I told him we didn't deliver but the other store did. He asked me to make an exception because he just lived 2 houses down from our store.
Then get off your ass and walk down here to get it! And if you can't, just have it delivered from the other store.
Although we did make an exception for the firemen across the street, but the reasons for that are pretty obvious...
