Probably a lot more honest folks up there. That didn't work well down here.

Having taken many a 911 call from gas station clerks in the Bay Area who had motorists drive off without paying, I can see why you just can't pump what you want in the Bay Area, at least, without some type of deposit up front. My PD stopped responding to these gas drive-offs a good dozen years ago as they just wasted too much of our time and occurred several times a day, sometimes with fraudulent license plates used, and once in a while a stolen car. It did cause the offending stations to upgrade their equipment so that a motorist couldn't just drive in, pump $100 in gas, and drive off. Maybe it's not an issue north of the border, but it was a big problem down here and threatened the financial health of some service stations.
