Some people just want to "steal" things and aren't happy unless they do. You get all kinds at yard sales - that's what makes them interesting. There are those that will pay whatever the sticker says and those that will try to get $100 items for $1.00. There is no reason for people to be rude, though. We had a lot of model staging items for sale in our last sale and had a couple of women scoffing at the pennies on the dollar prices I had them marked at. I wasn't sad to see them leave - empty handed.
