allow a merchant to ask for my ID. If they do I get in High "Who the fuck are you"mode. I have a credit card that allows the checker to compare my sig and either make the sale or refuse it. If stuff is stolen it is because the card holder is not aware o the theft and doesnt report it. Keeping your 1 credit card maxxed out :-) prevents theft. You have much better defences against theft than a debit card.
I love self checkout, I dont have to wait for the dumass clerk to finnish making a date for the evening, talk for 1/2 an hr to the mook in front of me because he/they are clueless and changing the tape when I arrive. I can enter a store, buy what I wish without ever interfacing with a minimum wage ghoul whose whole aim is to end the shift with the least work possible.
thanx,
bill
