Will a cab show up faster if the bartender calls?
*any half-decent bartender at any half-decent bar is going to be smart enough to call you a cab, for exactly the reasons item pointed out. any half-smart cab company is going to want to develop that bar relationship as well – drunk people tip better. hell, in nyc, i know cabbies that get paid by bars / stripclubs for referring / delivering riders *to* the paying establishments, let alone back home from.
