My experience at Costco is usually very nice, however today's experience was terrible. All was well until I tried to enter to help out my mother with her cart. An employee, Jenny to be exact, was more than disrespectful to me. She told me I was not allowed into the building because I was under 18, which in fact was wrong because I am. I told her the circumstances, and she refused to allow me to come in. That was fine until she put her arms over my chest and pushed me back. This is not the customer service I pay for. I am very disappointed in this service, and I hope that's this issue with Jenny is resolved.
