On dairy, doorways, and drinking
When walking through a gateway to another room, i.e. a doorway, check yourself for a change in altitude. It is often unmarked and can take down even a giant.
Clubs here charge substantially more for, I'll use this term loosely: delicious bevvies than even the nicer places in Madison, approaching NYC levels. But, even the bartenders at a venue like Zouk can crack under a little bargaining pressure (margarita pitcher with 1.75X the alcohol). Be sure to hold your money until the last possible moment, after services have been rendered. You hold more power that way.
