I have very good reputation for Costco service until today the gas station person started to threaten to cancel my membership. I and my friend went to fill gas at the cedar park gas station. We both were on two different cars and we were filling gas for both the cars after a long day of work. We used my membership and my card to fill gas for both the cars. The person at the gas station walked to my friend and said that we cannot fill gas in same membership, even though the member is physically available. I don’t know what’s wrong with this. It was a very bad experience at the gas station for the first time in my life. I have been an executive member with Costco for about 3 years and I am not allowed to fill gas for two cars. I know Costco sells gas at competitive price, but for few cents getting threatened for membership cancellation is not acceptable from a customer stand point.
