Also gotta love the customers who walk up to a build-your-own style line and rattle off every single ingredient immediately, instead of allowing you to build it, one section of ingredients at a time, as the whole business model is intended. But then it's somehow your fault if it isn't built right and they're annoyed about repeating the ingredients.

If people can't slow down just enough to allow the employee to correctly do their job, they should really just go to a place with a #1/#2 style ordering option and make everyone's day simpler and easier. Trying to dump information on the first (but possibly not last) employee they encounter just makes their order take longer.
