That's normal behavior for the young staff, however they are usually prepared with a mat type menu.
Typically this is a very good chain. The menu is at most locations across the country where you place your order. They have a concept where they're trying to get you through the line as quickly as possible and they servers usually have menu cards if you're not sure what you want. I encourage you to try it again and download the app you can earn free food. I apologize for your bad experience but it doesn't happen to often at any of the restaurants.
