I recently went to a gas station where the pump worked right! No affinity cards. No car wash offer. No asking for a ZIP code, since I'd been there before. No screen with ads. Press card against RFID reader, select octane, pump gas.
I went inside and complemented the worker on their pumps being so easy to use. I go back there occasionally, even though the station with the ad screen is cheaper.
nah - gas pumps that ask for phone numbers for savings card id's are great opportunities to save cents at the pump. 555-555-5555 always works everywhere and half the time gets you savings.
