Dear Paxy, I agree with Aunti Leela, I think if they have a hard time with your fingerprints, its either the machine, or your fingerprints are just naturally hard to detect for some reason, not a big deal.
I too, wash my hands a lot, sometimes I wonder if its too much, but after touching food, the computer keyboard, the clicker for the TV, the garbage, or wiping of a counter, just sounds normal to me! My boyfriend says its too much, but I say thats just his opinion. I was very sick once, and didn't want it to happen again. So I became very germ conscious. Doesn't sound like a problem to me!

P.S. Shout out to Auntie Leela, thanx for all your help!
