Why is it so difficult to use the correct fuel can? I work in a convenience store and we are to stop the fuel dispenser if we see someone putting fuel in the wrong type/color container. We also hit the stop button if someone starts pumping fuel and they walk away from the vehicle. Someone smoking while fueling their vehicle causes us to hit the STOP ALL PUMPS panic button. I guess some people are stupid. Last year in our town, a business owner lost his entire business-pumps, building, everything. So we react fast. If someone complains, we call the city fire department and let them explain while they get the ticket.
I guess some people know more than everyone else and the rules don't apply to them.
