On the Crowdsauce CZ group, the picture of the sign was flagged as abusive and removed by Facebook.
I took a stroll by Our Café earlier this morning to see if the sign was still in place. It is, and there’s another parking sign in far better taste a few meters away from it.
Maybe it’s just a joke gone horribly wrong. We reached out to Our Café via Facebook earlier today but have yet to hear back; I’ll update this story if and when they do write to us.
UPDATE: According to recent posts on Crowdsauce, as of 11:30 this morning the sign has been removed.
