Quick Thinking

John works in a supermarket. A man came in and asked John for half a kilogram of butter.
The boy told him they only sell 1 kg packets of butter, but the man was persistent.
The boy said he'd go ask his manager what to do.
 
John walked into the back room and said, "There's a bloody fellow out there who wants to buy only half a kilo of butter."
As he finished saying this, he turned around to find the man standing right behind him, so he added, "And this gentleman wants to buy the other half."
 
The manager finished the deal and later said to John, "You almost got yourself in a lot of trouble earlier, but I must say I was impressed with the way you got yourself out of it.
You think on your feet, and I like it a lot. Which place are you from?"
 
John replied, "I'm from Mexico, Sir."
 
"Oh, really? Why did you leave Mexico?" asked the manager.
 
John replied, "They're all just prostitutes and soccer players up there."
 
"My wife is from Mexico," the manager said.
 
John replied, "Which team did she play for?"
