So far my list includes Comcast, EA, and Nestle. Tell me yours, and I’ll help out.
You do need to be a member, or accompanied by a member to enter the building and buy it though (at least where I live, perhaps this rule is different in different places?)
If your local store isn’t following Costco’s policies, that’s not Costco’s fault. Report them if you really want.
A membership is absolutely not required to use the “food court”. The machine doesn’t scan or use your membership at all. The rest of your complaints are equally bold faced lies that don’t in any way match Costco’s policy, or full on unhinged lunatic horseshit.
At all the Costcos where I live, there is staff rather than a machine at the very front door that prevents entry without a membership, even to the food court. I think it’s much more likely that their policies vary from country to country, rather than their being a rogue sect of policy breakers in my city. I don’t think my view of Costco based of the customer experience I’ve had there is any indication of lunacy, I’ve had a bad time there, and so it’s okay I don’t like it. Just like it’s okay that you do. I’m glad you’ve seemed to have had a more positive experience, and they definitely do treat their staff better than some. My issues with subscription based models, and land development with Costco remains though and I don’t think my opinions changed.
I hope you have a good day and that people’s differing opinions on Costco isn’t nearly so upsetting for you in the future!
