She said, "Sorry about the wait - the drive-thru has us totally backed up on tacos, and... she doesn't like being helped."
It was several more minutes before we got our food.
I'm sorry, if it's the lunch rush and half your food service is getting backed up, you are just going to have to learn to work with other people.
So that's a suck from the person who is apparently cranky and refuses help, and a suck from the manager who doesn't put another person on tacos when it gets so backed up that it takes NEARLY TWENTY MINUTES TO GET OUR FOOD.
We didn't bother complaining because it was obvious they knew about the problem and were not doing anything about it.
