Yesterday I went to CostCo to fill up my car with some gas. And one of the reasons I applied for the membership with CostCo is for the lower gasoline price. Unlike in San Franciso (I lived there for several years and just moved back to Sacramento recently, but that's another story) , almost every CostCo here is equipped with a gas station and definitely shorter waiting lines at the pumps. Anyway, I pulled into the gas station and wasted no time at all to start pumping gas. Right after I got out of my car, I heard the "thug... thug..." noise coming from the pump next to mine. It was the sound of topping off the gas and it was from an old gentleman. I believe he squeezed the gas pump trigger at least four or more times. "Isn't it a bad idea to top off...", I was wondering. There, I saw it, clearly stated at the gas pump: To avoid spills, please do not top off! I guess it's kinda OK to top off once or twice, but four or more times? How much further can that little extra ounce of gas will make the car go? I am not over reacting to his action, I just think it's kinda funny. This also reminds me a funny or strange scene I encountered in San Franciso. I saw a guy sticking out his left foot out his car window and rested it on top of the side view mirror while he is driving! It's an amazing feat to me. What happened to his common sense? Does he care about what others think about him? I sort of understand that sometimes a car passenger might want to put his or her feet up on the dashboard... Anyway, maybe I am just nick-picking too much.
