A man walked into a department store. He spotted a woman at one of the desks and approaches.
"Excuse me, miss. Do you guys sell grapes?"
The woman, confused, was apologetic in her reply. "I'm sorry sir, but we don't. This is a department store. We have clothing, shoes, and a few other things, but we don't sell produce. I'm sorry."
The man didn't seem troubled by the response. He cheerfully bid her a good day and left.
The following day, the man again entered the department store. He found the same woman at the desk, and he approached her.
"Excuse me, miss. Do you sell grapes?"
The woman, even more confused than before, chuckled. "Weren't you in here yesterday? I'm sorry. We don't ever sell grapes. It's just not something we have here. Sorry."
Again, the man thanked her with a smile and went on his way.
The next day, the man again entered the department store, found the woman, and approached her.
"Excuse me, miss. Do you sell grapes?"
The woman, showing a mixture of bewilderment and frustration, still managed to keep her composure as she replied, "No, sir. We do not sell grapes. No matter how many times you ask, the answer will still be no."
Unfazed, the man smiled, thanked her, and left.
The following day, yet again, the man entered the department store, found his favorite lady, and walked up to her to ask, "Excuse me, miss, but do you sell grapes?"
The woman, now visibly upset, replied, "Sir, I think you've asked enough. We do no sell grapes. I'm going to have to ask you to leave."
The man replied, "No problem. I'm sorry for the trouble," and left.
The next day, the man again entered the department store. He spotted the same woman behind the counter and approached, asking, "Excuse me, miss. Do you sell grapes?"
She went berserk, "NO, YOU IDIOT! WE DON'T SELL GRAPES! WE'VE NEVER SOLD GRAPES! WE'LL NEVER SELL GRAPES! IF YOU COME IN ASKING FOR GRAPES AGAIN, I'M GOING TO NAIL YOU TO THE WALL! GET OUT! NOW!!!"
The man, completely ignoring the yelling, politely apologized, thanked her, and left.
The next day, the man came in and found the woman. He approached the counter, and before he even got to the desk, she spotted him and and became upset.
As he reached her, he asked, "Pardon me, miss, but do you sell nails?"
Already angry, she shouted, "NO!"
He then smiled very widely and said, "Good. Do you sell grapes?"
