It happens even in Minnesota Nice-land...at least most times when it's freezing people get to sit in their warm cars.
However, sometimes the stations are at fault, the Holiday by my house will only do the end pumps if you pay inside, or pay via credit cards. So some people that don't know this will pull up, get out, try to fuel, and then get the "please pre-pay, or pay via credit card on the end pumps", then go inside and do just that.
There isn't a sign that states it, and the last time three years ago I pointed that out, I got a shrug from the employees.
