It’s hard to cause a large gas explosion by carrying a flame. Gas tends to diffuse, so you get small explosions that dissipate the problem before you reach the large concentrations.
That said, “hard” does not mean “impossible”. History is full of counterexamples. But it is much easier to make trouble by igniting the flame after you are inside.
Smoking a cigarette won’t cause a fire at a gas station.
Lighting a cigarette, on the other hand, can absolutely cause one.

Yep a cigarette cherry is not hot enough to ignite gasoline.
Which is how the human race survived for a long time, I very much remember smoking at gas pumps being a norm in the 80s.
No, it definitely is. It’s just that gasoline is relatively hard to ignite and the right air/fuel mixture won’t reach the hotter part of the ember.
