Daily Cuts - Is 'tailgating fee' common among gyms?

Do you normally check if the door is closed behind you when you're at the gym? The big question is - is it even your responsibility? One gym member from Anytime Fitness had to pay $60 ‘tailgating fee’ because an unidentified woman entered the gym behind him without using her own key fob. Anytime Fitness ended up apologising to the member. But Ken Mok, Owner and CEO of Fiitboxx says he doesn’t think the onus is entirely on the member to make sure there is no tailgating.
