Where there is a pong table, the beer would surely follow.
In all no nonsense though, I would not like to see a ping-pong table at the store. I have an equation for this:
Adolescents + Paddles and Moving objects + Mountain Dew = Mass Destruction and Reprimand
It would be too much to monitor, accidents will happen, and you cannot restrict the table to certain individuals because you have to be fair & honest to the mass majority of all the consumers of the store.
I apologize for being a downer on this one, because I would love to play pong if the situation was better suited for it.
