A traveler was stumbling through the desert, desperate for water, when he saw something far off in the distance.
Hoping to find water, he walked towards the image, only to find a little old peddler sitting at a card table with a bunch of neckties laid out.
The parched wanderer asked, "Please, I'm dying of thirst, can I have some water?"
The man replied, "I don't have any water, but why don't you buy a tie? Here's one that goes nicely with your clothes."
The desperate man shouted, "I don't want a tie, you idiot, I need water!"
"OK, don't buy a tie. But to show you what a nice guy I am, I'll tell you that over that hill there, about 5 miles, is a nice restaurant. Walk that way, and they'll give you all the water you want."
The man thanked the peddler and walked away towards the hill and eventually disappeared out of sight. Three hours later he returned.
The man at the card table said, "I told you, about 5 miles over that hill. Couldn't you find it?"
"I found it all right. They wouldn't let me in without a tie."
