I NEED CLEAN

I thought I was going to have a calm Saturday after the tablecloth lady but no. I was introduced to the most stupidest person on this Earth. I will call him the Fail Guy. He deserves that title!!

What did he do?

Many things. This is how it goes:

Failguy: I need clean.
Me: Excuse me?
FG: -mumbles-
Me: -snaps- What?
FG: You have clean?
Me: -points to the soap- You need soap?
FG: -nods-
Me: Which one?
FG: Tide
Me: Okee... 6.50

After giving me the money he left and I thought "that wasn't so bad... he won't bother me again". Five minutes later:

FG: Clean no work.
Me: What?
FG: 18 clean no work wrong
Me: Is something broken? Did you break something?
FG: no clean no clean!
Me: Okay, okay... show me!

So he takes me to the washer and he says that he put the coins and soap in the wrong washer. This is how it all unraveled:

FG: Clean in wrong machine
Me: You put money in here too?
FG: Yes, 2.50
Me: I can't give you your money back. I don't even know if you really put it in there! Plus, I am not going to pay for your mistake!
FG: ok, give me free clean!
Me: No! I am NOT responsible for your mistake! It is YOUR fault! You should have paid attention. You need to pay attention to what you are doing.
FG: I need clean.
Me: I will sell it to you.
FG: Give me discount.
Me: No, I am not going to be responsible for your wrong doing! No discount for you!

Finally he starts to put money in the right washer and he comes to buy soap. He is about to walk away with it for free but I told him to come back and pay. He did pay. I thought that after that, he wouldn't bother me again... he did.

FG: Clean no work
Me: What?
FG: 18 no work
Me: Ugh! Show me!
Me: You didn't close the door!
FG: OH okay!

His friend was sitting down and tells me "he is stupid." I replied "no shit". And we left it at that.

Oh and if you were wondering, "clean" used by him means soap and washing machine at the same time.

So, when can I grow a new set of brain cells?
