I Only Have...

A man on a camel rode through miles of the sun-drenched
desert searching for some sign of life. His supplies were
running low when his camel died. Now on foot, he desperately
sought refuge from the heat, and, most importantly, a source
for water. Suddenly, he came across a vendor in the middle
of the desert.
"I'm so glad I found you!" the man cried. " Please help me.
I'm in dire need of some water."
"Well," said the vendor, "I don't have any water. But would
you like to buy one of these fine ties."
"What am I going to do with a tie?" the man asked.
"That's all I'm selling sir. If you don't want a tie, I can't help you."
The man left the vendor and walked on for many more miles,
praying each minute that he would find refuge from the scorching
sun. His eyes squinted a bunch of times when he came across
a restaurant in the distance. Unable to comprehend a restaurant
located in the middle of the desert, he assumed the place was a
mirage, but decided to check it out anyway.
As he approached the door, his mouth opened in amazement,
seeing that the place actually existed.
The doorman stopped him before he entered. "Excuse me sir,"
the doorman said, "But you can't come in here without a tie!"
