Looking for a clean bathroom in a gas station these days? You might have to drive to LA. Paul Moghadan's Grand Plaza Chevron station off of I-10 in the suburb of West Covina features a chandelier, sculptured art, a floral arrangement, silver columns, an Italianate slate floor, a wide granite counter, and rosa marble walls. Gold-plated fixtures grace the sink. The room is 10 feet wide! Moghadan says, "I started with Chevron in 1966, and they trained us back then that the No. 1 priority was the station bathroom." "I have customers from Palm Springs and Las Vegas who make a point of stopping here. Some even bring in relatives to show them the bathroom."
