A week ago, while I was on my way to work, the "low fuel" light on my car turned on. So, I decided to go to Costco to fill up. Got there, filled up, hopped back in my car, and it wouldn't start. It was dead. D.E.A.D. dead. :( The attendant was awesome. He quickly ran over and helped me push by behemoth of an SUV out of the way, so as not to block the pumps. He even asked if I needed to call someone for help. I really admire the caliber of employees Costco hires.
The reason I only give 4 stars is that the location is terrible. It's in an awkward location, which prevents easy access.
