One day a rabbit walked into the butcher's shop and asked the butcher, 'Do you have any carrots?'
The butcher replied, 'No, I'm sorry, sir, but this is a butchers' shop. We don't sell vegetables in here. Go to the greengrocer at the other end of the street. I'm sure he's got some carrots.'
The rabbit thanked the butcher and left the shop.
The next day the rabbit went into the butcher's shop again.
'Good morning! I'd like a lettuce and some carrots, please.'
'Look, I'm sorry, sir! I told you yesterday - we don't sell any vegetables in here, only meat.'
'OK, I see,' said the rabbit and left the shop.
