Sad to hear that the folks at the show didn't do better for you. It is kind of funny because I moved to York area about 20 years ago and one of the first things one of my neighbors told me is people in York area are "cheap". And I noticed over the years that I had lived in that area he was right. Everyone was nice but if you wanted to get a dollar out of someones pocket you better be willing to work for it.
I think the difference with Allentown is it is closer to Phila & New York so people come into the Allentown area and everything seems cheaper to them then what the are use to further east. York on the other hand gets more of the rural Central PA crowd and they are a little more conservative with their cash.
Just my observations being from NJ originally and being a "transplant" to Central PA about 25 years ago.
