Why would they make it illegal in those places? I never hear of fires or explosions at gas stations around here even though most people fill up at self-serve.
Full-serve exists and it's a few cents more per litre, but I never bother to get it. My mom used to for a long time before gas prices got ridiculous, and the area around her car's fuel filler is completely snatched up due to careless 14 year olds pumping her petrol.
I don't think many here go to full-serve often. 'What I hate about getting gas here is, about eight years ago they removed the locks from the gas pumps so now you need to stand there for 5 minutes holding the damn trigger. I think it's something about keeping people focused or some shit.
Anyway, I like pumping my own gas. Makes me feel manly, and I love the smell of petrol.
