JT sitting on countertops

Today I’m sick at home binge watching this season and I am so bothered by this man sitting on countertops. Who does that? He did it at the golf simulator and had his legs fully laid out on the bar top and now he’s doing it at the tuba after party. What grown man sits on countertops? Is it his way of making himself taller? If your leg is so hurt that you require a cane to walk I don’t see how jumping up on a counter is easier than sitting in a chair.
