It sounds like you have a realistic approach to selling at train meets.
As for the folks on the other side of the table, there are all types out there. I sell quite a bit, and I run into some folks that just need to negotiate or they won't buy, and others that know the value of the item, and will jump in with "I'll take it" if the price is good to them whether it's as marked or talked down. Then there are others that play the "would you take__________?" game, and even when I agree, they say, "OK, just wondering". I used to let some get me upset, but now I just figure the whacky ones give me great stories to share.
