Are you really "getting ripped off" if you came in with a ridiculously high offer (when no one asked) and they accepted it because they'd be crazy not to?

"I've got this old beater that I'm tired of working out of every day."

    Your food truck sucks and your food is no better. You should sell churros.

"Churros don't really match our poboy sandwiches."

    I can fix this, I'll just buy you out for a million dollars.

"... ok, sounds good to me."

    What do you mean the truck is only worth about three grand? I want out of this deal.

"Here's the signed contract..."

Indented guy above didn't get ripped off.
