Arloo joke of the day-9

Separated from his travel group in the Sahara Desert, a tourist begged a passing nomad for water. "Sorry," said the tribesman. "I have no water, but I do have a selection of lovely ties for sale.""You must be crazy," the tourist replied. Close to death from thirst, he saw another nomad. "Water!" he gasped. "Give me some water.""I have no water," came the reply, "only these handsome ties that I'd be glad to sell you."The tourist stumbled on until, to his astonishment, he saw a magnificent hotel far in the distance. Crawling at last into the lobby, he croaked, "Please give me water.""I'm sorry, sir," the doorman said. "We don't let anyone in without a tie."
