Never panic--believe in presence of your mind!!.......In a shop a man asked for 1/2 kg of butter. The salesperson, a young boy,said that only 1kg packs were available in the shop, but the man insisted on buying only 1/2 kg. So the boy went inside to the manager's room and said 'An idiot outside wants to buy only 1/2 kg of butter'. To his surprise, the customer was standing behind him. So the boy added immediately, 'And this gentleman wants to buy the other half!'.After the customer left, the manager said 'You have saved your position by being clever enough at the right time. Where do you come from?'.To this the boy said, 'I come from Mexico . The place consists of only prostitutes and football players!'.
