A drunken man walks into a coffee shop one day.
"Do you have ice coffee?"
"No sir. We don't." Says the owner.
"Ok then." says the drunken man.
Then he gets on his way. 20 minutes later he comes back in.
"Do you have ice coffee?" he inquires again.
"No sir. We don't. I told you before." Says the owner.
"Oh. Sorry about that." says the drunken man as he waddles off.
20 minutes later he comes again.
"Do you have ice coffee?"
"Sir, I told you before. We do not have any ice coffee."
"Wow ok then. No need to tell me twice!" exclaims the drunkard and exits.
This time, the owner decides to put some coffee in a bucket of ice and wait.
Sure enough, 20 minutes later the drunkard enters again.
"Do you have ice coffee?" he inquires.
"Why yes sir, we do!" says the owner with a smile.
"Ugh, could you heat a cup for me then?"
