I arranged for a cab pick-up for 4:10 PM, confirmed with the girl who called me. I just got a call at 4:15 PM from my driver saying he would be here in "10 to 12" minutes and that he had just gotten the job. I have a flight this evening and arranged the time so I would be at the airport 90 minutes early and now I may not get there 'til 45 minutes before my flight. What is the point of arranging for a cab for a certain time if drivers won't even be dispatched until after that time?
