What? Not necessarily at all. Say I have a bar that is completely dead on a Wednesday night, due to it being Wednesday night and it being in some off part of town.

I could advertise that I have some free jam space for musicians, a drum kit and a PA with a few microphones and maybe some guitar/bass amp or speaker cabinet. Maybe people will show up to make some noise. Those same people (and maybe a few of their friends) will buy a few drinks, and that's where the "enriching my business" part comes in.

Nobody is required to buy a drink, and so this is a better offer than them having to actually rent equipment and room.
