Big box home improvement store. If I worked for a wargaming store I would have a lot more wargaming stuff and wouldn't be so cross while at work. Mind you, I would also be flat broke 100% of the time.
This is why I don't own a 3D printer. I would be tinkering with models from armies I don't play. That and terrain would be overrunning my house.
I can just imagine that trio singing 'Jedi Rocks' with that massive speaker blaring it out across the battlefield. That'd be enough to break the morale of any enemy with decent hearing that can't be voluntarily switched off
