Throwing punches outside Gem Spa

I usually don't pay much attention to that Boxer game here at Gem Spa on Second Avenue and St. Mark's Place... it's usually hidden behind displays of hats and sunglasses during most of the times that I pass by...



But not always!




Is this really a good idea to let people get worked up and pay to throw some punches...? Or is this actually a good idea because any drunken aggression may be taken out on the machine? Dr. Grieve is now in session.
