Rumor's that the regulars threatened to go to some other tavern if the owners kept giving all their stock to 'no-good fauns.' Between that and driving people into debt with you and the tab...

[ It's easy to see the multiple ways that this could've ended up happening. If just the mirrorbound fauns alone decided to crash a tavern for a while, to see how far they could go, it'd leave the place dry until more stock had come in again. Judar might've done the latter, which got him the drinking contest ban. ]

But as bambi's demonstrating already, sometimes fauns just can't help but toy with rules for a good time.
