I would prefer a place is expensive enough to keep the riff-raff out, and freeloaders are simply kicked out. An expensive place can always drop its prices on slow nights.
On the other hand, most western places in Taipei are at the same level of expensiveness, and the riff-raff have to go somewhere. A saturday night at Carnegie’s or the Tavern, or the Brassy or wherever should be setting people back over NT$2,000, and that’s I imagine what the landlord is looking for as a good average. It is up to the publican himself is it not to identify the regulars and treat them right, whilst keeping an eye on the Coke-sharers.
I am well known at Carnegie’s, on the other hand, but do not frequent the Tavern because, simply, I am not a sports fan. Apart from rugby, for which I usually go to the Brassy or JB’s. If I turned up at the Tavern, TC might have a good long look at me, and tell me to eff off if he thought I wasn’t drinking enough. However, I am a monster raving alcoholic, and once you get me in there I’m unlikely to leave until I run out of money or Amex finally gives up. So why don’t you Laobans come up with an inter-pub Big Drinker’s Card (with drunken photograph) so that gin-soaked wastrels who are intent on pissing all their money down the drain are universally welcome, but the 7-11’ers and Coke-sharers aren’t?
