American Pax
This might sound awfully cruel but i do enjoy playing a joke on American SLF,
Pax: "Can i get, like, a coffee?"
CC: "Certainly, we have tea."
This can be adjusted and adapted to more or less any request.
or my personal favourite:
Daughter: "Can i have a water?"
CC: "No problem, Regular or Diet?"
Daughter? "Wow, Diet Water? Mom! Mom! They do Diet Water!"
Mother: "OMG Diet Water? Can i get one to?"
