A few years ago I attended a well known Southern California train club's monthly meet in the Orange County area. I was not a member of the club but attended as a member of the general public.
I saw a box car I wanted on a seller's table, of course none of his items were priced. I asked "How much?". The guy says "30 bucks". I told him I would take it and I got my wallet out. It was towards the end of the meet and I had exactly 29 dollars on me !
He said " I can't sell it to you for that"... I was going to tell him to hold on to the car that I would go out and check the seat cushions in my car for the extra change, but he literally turned around and started talking to his table buddy. I was dismissed!
Needless to say I never went back...
