Question

There was a man walking in the desert. It was an especially hot day that day. In the distance, the man suddenly saw a restaurant. He rejoiced and ran to the restaurant and immediately asked the waiter for a glass of water. Instead, the waiter pulled out a gun and pointed it at the man's head. The man replied with, "thank you". Why did the man say "thank you"?

Answer 1

Because he sprayed him with water to quench his thirst.
(the gun was a water gun)
I hope this helped!

Answer 2

The man said "thank you" because since he is walking in the desert and asking for glass of water so he has to be thirsty. When the waiter pulled out the gun and about to kill the man , he rather die than to live of thirst.
