Come on man, you blocked his car in with your car and refused to let him leave until he paid you? That, my friend, is a crime in itself.
Then when you had him cornered, insisting he paid you, you got his watch out of him. That, my friend, is extortion.
Besides, you already agreed earlier in the thread that you are an idiot. Can't renege on that now. Oh... and you can't write for squat. So, perhaps it is YOU that needs the lessons in reading/writing.
Let me just say, there are people in the business next door who have been there for years. I know them and know them well... but I sure as hell wouldn't front money for them to purchase something. I don't give a damn who it is, we get a 50% deposit on everything we do. That deposit will cover any loss we may take on materials if the customer walks.
I stand firm. You are an idiot.
