I just noticed in the last month or so, gas stations are flashing 2 different prices, when I still had my business, in the old days, when credit cards were all handled by hand, and at a cost to the merchant, I made it very clear, that I wasn't going to be the one who took it in the shorts when card was flashed, some people actually thought I got paid for taking them, the margin was really short to begin with, so to keep the doors open, it was a necessity.
