Depends...
If you have regular gas stations you attend and can keep track of what those gas stations do or don't do. Regardless of what they say they do.
Jusr make sure there is no hidden agendas.
But then again, some people will just buy something for the attention that surrounds the purchase, so if it's a fishing town...maybe?
And yes, some will buy to try something new.. or to make a point that they can catch on something diff.
Beenie Weenies and corn niblets also work good, so I'll stick with them from my country gas stations THAT I ALWAYS GO TO.
Just making sure noone goes home empty fishing handed is the best advice i can think of for gas stations.
They are not the best place for lunch dates though, i can tell you that.
Unless they got them killer crispy bean burritos.
