I don't work in the restaurant industry anymore (thank god!), but I still work in customer service. And we absolutely get those insane things customers say.
My coworkers and I were going on about our customers (no customers around) and one lady complained about the fact we have “too many broken crayons”. One of the employees apparently talked to a kindergarten teacher afterward and said teacher purposely breaks the crayons halfway through the year because it apparently helps with their fine motor skills. lol
I don't know if that's really true, but the next time I hear a complaint about broken crayons, I might just use that as my excuse. lol
