Not if you put Baileys in it! On my IAH-SAT RT had the same crew both flights. Asked for an "Irish coffee" (thinking that was Baileys and coffee) and the FA didn't know what that was. She asked the other FA who happened to be Irish! He said, "Well, it can be with whiskey or Baileys, but technically it's with whiskey." I had to say, "Well, I guess I want the non-technical Irish coffee." Had one pre-flight and one in the air both times - great way to start the day!
