A Combo Of Errors

(I go to a fast-food drive-thru on a busy Friday night. I order a combo that has a burger, fries, chicken nuggets, and a drink. I say how I want my burger and what I want to drink, and then I pull around.)

Worker: “Your total is [less than it should be].”

Me: “That was for the combo meal?”

Worker: “No, that was just for the burger and the drink.”

Me: “Okay, can you change that to the combo, please?”

Worker: “No, I’m sorry; you are going to have to get back in line.”

Me: “Really? There are, like, four people behind me.”

Worker: “Yes, we can’t change the order here.”
