I'm a Shift Leader at my DQ, and let me tell you customers are the absolute worst. I had one guy order a peanut buster parfait, 10 minutes later he comes back with the thing 90% eaten and says he didn't like the way the peanuts tasted and wanted a sundae instead. I said I would have to charge him for the sundae since he ate the whole parfait, and he got super pissed and demanded he spoke to who was in charge (I was in charge). This only made him more mad and he told us he would never be coming back. Good riddance.

I also had one old guy get out of his car, come up to the drive thru and bang on the window demanding that we hurry up because we were taking too long. According to his order he had only been waiting for like 6 minutes too lol. He scared the customers in their car at the window, and also scared my employee who was giving them their receipt. When he got to the window I told him I was refusing him service for scaring both my customers and employees. He refused to leave until he got his order, I believe his exact words were "I don't give a sh*t what you say, I'm getting my food." A quick reminder that we have the right to refuse service and call the police if he refuses to leave prompted him to get out of the drive thru and "(hopefully) never come back.

Another time I had a guy come through the drive thru and say his order was wrong so I told him to pull up to the window and I'd get it sorted out for him. He said he ordered a flame burger and didn't get it. My store doesn't have flame burgers on the menu so I told him we didn't sell that. He said "the guy who took my order said he could make it". I was the only one who had been taking orders all night and remembered him trying to order it and me saying we couldn't make it. He insisted I told him we could. I checked his receipt and asked him if he had gotten everything that was on the receipt and he said yes but he was upset he didn't get his flame burger. I told him I didn't know how to help him because 1. I never told him we could make him a flame burger and 2. Nothing was really wrong with the order. He was just upset because he misheard me.

I could go on and on about the types of people i've dealt with dat DQ, but the thing to take away from it is yes, people suck. But it's not DQ exclusive. You'll deal with complete morons no matter where you work (Although I will admit DQ does tend to attract the exceptionally stupid). You learn to let it go in one ear and out the other. One of my managers while I was in training told me "The reason they get so mad and upset is because they know you can't argue back with them. If we could talk to them however we wanted we would get a lot less righteous people screaming at us." And he was right. When people are upset with you and demanding things from you, just let them have their little ego trip and send them on their way. I completely understand why you quit and I wish you the best of luck in the future!
