Gas smell in my car

[TxBandit]

Hey guys. So here's the deal. Recently, every time I fill at the gas station, I get a gas smell inside the cabin when I leave. The smell persists for several minutes and slowly goes away. Sometimes I have to roll the windows down for a few minutes to get some fresh air in because it's gets pretty strong.

I've looked under the hood but don't see any visible leaks. I'm baffled. What do ya'll think it could be?
