Will a cab show up faster if the bartender calls?
Also, if the bar staff in your bar are anything like me, they’ll not be pleased to be asked. I’m glad none of the drunks I know and care about frequent your bar. In my experience working at very busy bars, we always wanted to make sure that our patrons got home in one piece so that they could come back and buy more booze. I was happy to call a cab for someone – it didn’t mean that I’d drop everything to do it and it definitely didn’t mean that the car would come quicker than if the customer had called, but it’s a service that was always there.
I used to work as a taxi dispatcher. Having the barstaff call did not make any difference, unless the taxi was specifically ordered for staff. I guess barstaff are too busy to notice how long a customer waits for a taxi, but they know how long their own takes to arrive. Nowadays, more and more taxi firms are moving to GPS- enabled automated dispatching systems. Obviously, these don’t care who calls.
