Politely Pumping

As the last notch on my digital gas tank was angrily flashing at me, I pulled into the nearest Shell station to fill 'er up. After swiping my card, pumping the gas, and returning the nozzle, the gas pump machine asked me if I wanted a receipt. My options were "Yes" and "No, thanks." I thought, well isn't that nice? Shell is teaching folks manners! But I wondered, why not the affirmative option, "Yes, please." It goes both ways, Shell! Oh well, at least the negative option wasn't, "No way, you jerk, and screw you for even asking!"
