I did back in High School. It was actually a pretty sweet job. Not too overwhelming and not that hard of work.
Just don't be a super lame employee. Have a personality, greet people and smile. Do work when it needs to be done. I f'ing hate walking into a gas station and the guy working there doesn't even look up from his magazine. And acts like I'm inconveniencing his day by paying for my gas or food.
i did for the 4 years i was in high school, such a sick job. it was privately owned gas station an there was only one person working at a time. my friends came every night i was working and we blazed. if it paid more, i would have never left
quite possibly the best threadjack in the history of ns. i call it Big Spences Big Fail
