I mean those point-of-sale terminals, in stores, although it's spreading to other things; we have a copier at work, where the display disappears after it's been off for a minute. You can tell where to turn it on by the big, greasy fingerprint.
But stores are the worst. It's not just touch once to get through it, either. Touch it put in your PIN number, touch it to go, touch it for no cash back, touch, touch, touch. Why don't they just ask us to lick it? It'd be as sanitary. I'd rather peel a tenski off a smelly roll of bills, than repeatedly press down on some grease-encrusted piece of plastic the whole neighborhood's had a whack at.
