From what I remember of working in fast food as a teenager, 3 things typically caused that situation.All fair points. Ive worked fast food and yes you make mistakes here and there. I assume if I'm going to a fast-food eatery that the food is subpar at best, but I'm willing to deal with that for the speed. When Im in a drive thru for 20 mins theres a problem
1. Someone called in sick, so service naturally took a hit. I had a situation where we were supposed to have 4 people working, 2 called in sick and we couldn't get someone to replace them since we were too busy trying to keep things going to go look up people's phone numbers and ask them to come in.
2. The restaurant I worked in had 6 fryer baskets, so if we got flooded with fried food items it just kept making the problem worse and worse since some items took 3 minutes to cook.
3. A surprise rush of customers. The whole point of fast food's quick service is to prepare things you typically sell and have them ready to go. During lunch time, you can usually just keep a basket of french fries going because you know they'll sell. But if a bunch of people come in at 8:30pm when you're not expecting many people it's going to take awhile to prepare their food when you have nothing ready. This is made worse when 1 and 2 are also involved.
