Fill Her Tank First
The summer of 1975 I’d just graduated from college in Southern California and received a 1968 Ford Capri for a graduation present. I had my first job, in Los Angeles. One Sunday night, __36__ myself a very independent grown-up, I left my uncle’s place in South Laguna after a visit, without __37__ to him that I had less than an __38__ of a tank of gas and no cash to buy __39__ on the way to L.A. I pulled onto the Pacific Coast Highway and watched the needle __40__ as I headed north. When I started running on fumes, I pulled into a __41__. There was no self-service __42__; there were no credit cards, no ATMs.
I begged the guy at the station. I __43__ write him a check for gas, I said, or I could sleep in my car and try to __44__ to a town with a bank the next morning. As he was informing me that I could sleep in my car but he’d have me __45__, a station wagon __46__ to the next pump. The driver--- a thin, plain, middle-aged guy---overheard the tail end of my __47__ request. As the attendant went to serve him, he nodded at me. “__48__ her tank first,” he said.
“Really?” I said. Hope __49__. “Oh, thank you. Thank you. But please. I just need two dollars’ __50__. I just need to go home.”
“Fill it,” he __51__ to the attendant. Then to me, “You will do the same one day, for someone else.”
I keep looking for that unlucky young person, __52__ to save her night on the road. Meanwhile, in case she never __53__ up, I try for other acts of random kindness. That __54__ driver is always at the pump a few feet away, __55__ the attendant to fill mine first.
