Osmolia's Service Station at 4801 Birney Avenue, Moosic, Pennsylvania.

This gas station (that uses Shell color scheme and has apparently nothing to do with Shell) tries ripping customers off by posting lower "self-serve" prices everywhere and quietly designating certain pumps as "full service", yet - unless you come here every week - you would never know upfront which pump would give you a huge surprise in the end. When I asked the attendant why the price was different without explicit notice, he started lecturing me in a rude way on how I should open my eyes READ "full-service" (somewhere in small letters on the side of the roof above the pump...) and thus UNDERSTAND the price would be different. Huh, seriously?
Avoid, there are so many nice gas stations around here - that's the first time in last 5 years I see BS like this anywhere
