I have been going to my gym consistently for about two years. I love it there, and I pay for a premium membership that gives me access to all classes, equipment, and even some personal training sessions. It’s not cheap, but I genuinely enjoy it and it’s part of my routine. A few weeks ago, my friend told me she had canceled her gym membership to save money. She explained that she couldn’t afford the monthly fee anymore but still wanted to stay active. A couple of days later, she asked if she could borrow my gym membership occasionally so she could come with me and use the classes. I turned her down, because my membership is non transferable, and sharing it could violate gym rules. I also I'm not okay to shoulder the cost while she got the benefit for free. I couldn’t let her use my membership. I explained that it’s against the gym’s rules, and that I also want to be responsible for my own payments and access. She doesn't seemed fine with it and pointed a finger on me and said your not a real friend! I tried to stay calm and didn't to anyting. I can’t risk losing my membership. I don’t think I'm wrong, at the same time I’m paying for my membership, and just following the rules. So AITA for saying no when my friend wanted to use my gym membership?
