No you're missing the point - when you make a purchase - USE the card. Screw the machines...lol Make the idiot behind the counter do the extra work scanning the card, extra steps through the "till and back up the line. That's the fastest way to hassle the IDIOT who's too stupid to give you correct change. When you tell them it's a credit card they have to hand ring it through - no PIN#s from you - just a signature.
