I had heard that one of the Nigerian assistant stewards was trying to learn english from some of the British staff on a Princess cruise years back. Everytime they would speak, he would ask what it meant. Sometimes he would just get the short and rather incomplete answer. For example they expained "Piss off" meant going to the bathroom. Well, one day a passenger asked him, can you please tell me where the nearest restroom is, and with the biggest smile he could muster the Nigerian pointed and said, "Piss off, thatta way!!!"
