More likely they were mocking you pumping gas. People stand straight up when they pump gas, they don't bend over, so you were deliberately giving them and your boys a show!
This guy and his friend were taking pictures of me, bent over pumping gas at the gas station. Oh and I was with my 3 young kids, who didn't understand why a grown man and his friend would be taking pictures of a woman bent over. At least I could use it as a lesson to teach my boys how not to treat a woman!!
