Especially because next to no one goes to the gym past 8-9pm anywayYeah, closing gyms at 10:00 PM doesn't make any sense. Gyms especially are 'all or nothing': either close them entirely or keep them open 24 hours (or whatever their regular hours of operation are).
You're gonna have a ton of people crowding up the gym at 8-9 trying to get their workout in when you could have had fewer people inside and more social distancing during the overnight hours.
Restaurants and theaters are whatevert ho.
