Yeah, I am not a fan of purell or giving antibiotics at the drop of a hat. I actually think it is more the merchandise than the money. I worked in a cash office for several years and money in general is dirty. I hated dealing with the 1s and 5s because they look ok alone, but when you get them all together it smells like skunk. So I think money could contribute but the real culprit would be the merchandise and table space on the edge that people run their fingers across when they are looking at other things further back or waiting to pay. Plus the merchandise goes from one convention to the next.
