We stopped at the Belton Shell on our way back to Iowa from Arkansas. The man working around 1:20 on May 22 was extremely rude to the point of growling and rolling his eyes at us when he gave us our change. Not to mention we couldn't get the gas pump to work. We mentioned it to him and he did nothing so we ended up only getting only $15. He didn't offer to correct the issue or even acknowledge it when mentioned to him that the pump wasn't working. Just looked up at the ceiling like we were annoying him. We ended up going somewhere else to continue filling he tank. He was preoccupied with a couple girls talking on the phone. Wish there was a negative spot for service.
