Very bad experience Since I am not feeling well, I had to send my son to the Costco with my membership card. The lady at the counter, she was not letting my son to use the membership card, both my son and I have the same last name., still she made such a big deal and acting like she owns the store. And she did not scan a bunch of banana and at the exit, they stopped him as if he stole a bunch of banana worth $1.99, and he had to go back to the line. This lady was so rude and arrogant, very first time I have this very bad experience from Costco at sugar and, Texas. Always I thought their customer service is great! Such a shame. I called the store to complain about this incident and whoever on the other end, didn't even apologize for their mistake. I am from Sugarland, Texas. I spent a lot of money in Costco every year shopping. I should stop going to this place, where they don't take care of their members. There should be a consistency when these people let others use the membership card. I knew many people use friends/neighbors' membership cards. I sent my son with my card, not any friends or neighbors. I hope and pray no one gets this kind of customer service. I am heartbroken from how my son got treated.
