Welcome to the Bar At the End of the Universe. Location: Between. Please do not try sending post here. The bartender is a tentacle monster and his favourite food is postmen. He finds their little white hats absolutely delicious.
And there is a Bruce Wayne, long sleeves and slacks, lounging at the counter, a drink in his hand. Is it alcoholic? Is it not? Who cares?
Come greet him. Or mingle amongst yourselves. Anything you wish.
Just don't make the bouncer throw you out.
