No, why would you? Attaching a cost to someone unable to visit the gym due to "overcrowding" wouldn't make business sense since you're unable to determine if that is actually the case or if they weren't coming for another reason.

A customer with a gym pays a monthly rate... That rate is paid even if they use it. The running cost of the gym remains the same whether or not someone comes to the gym.

This comparison, then, doesn't make sense. MoviePass is paying directly each time a customer uses the service. While both services are better off with people simply giving their money for something they don't use, only MoviePass actually LOSES money if people are using the service. The gym, on the other hand, doesn't.
