We've expanded into the unit next door (more office space and lab space now we have two units). As we now have a much larger "tea room", the boss actually thought it would be good to have a kind of "game room" area
The pool table was bought off eBay from a local firestation, and I think the table tennis table was an eBay job too.
I'm awful at darts (best kept away from it like you!), probably awful at table tennis, but used to be pretty good at pool.
