They will lose more customers than just furries.
Although honestly it would be funny if everyone went out and bout animal costumes and just piled into the place. Just order a drink and fill every seat and doorway in there.
It would piss them off and be hilarious all at once.
They won’t, you really, really, over-estimate how much people would care about weird fetishist people of which there are dozens, and how little of impact posts on the social media have on general public. And bad publicity doesn’t exist, so at worst they attract more customers due to being popular meme place where people are banned for ridiculous reasons.
‘weird fetishist people’ really tells a lot about you.
What exactly does it tell about me?
You’re a judgemental dunce.
That’s not a lot.
