A Sunshine Share-a-Cab

It’s an interesting premise: you call as you need a ride to the airport. They will pick you up and deliver you to the airport on the hour (i.e, 8:00, 9:00, 10:00) and only on the hour for a flat rate of 26 $. The catch: you may be sharing the cab with someone else.
I have used them quite a few times, and all was fairly positive for a small business. The man who takes your reservation (i.e., the receptionist) is a odd on the phone, which makes you feel a little uncomfortable as to whether they fully have your information for the reservation, BUT they do always show up to get you (albeit, usually a little late) so he’s obviously remembering your reservation.
My issue was with my last trip. It’s put me on the fence as to whether I will use them again. I was supposed to be to the airport for 8:00, and was told that my pickup time would be 7:15. At 7:20 I called as the driver had not arrived. The receptionist told me that he was running late and that I gave him the wrong number so they could not reach me. I later found out that he had written down my number as 998-​xxxx, rather than 999-​xxxx (I highly doubt that I told him 998). He told me that the driver would be there in another 10 minutes. When 7:30 came and the driver was still not there, I called back and the receptionist told me he would contact the driver to see where he was. When I asked him to confirm my number with me, he was, again, one digit off (making an 8 a 3).
The driver finally showed up at 7:45 and I was supposed to be at the airport at 8:00 (I live in the South end of Halifax). He ended up speeding to the airport and we arrived at 8:10 — 8:15. This was not a problem for me as my flight was 9:25, but if it were someone who was flying out earlier — that 15 minutes of lateness could have made them miss their flight.
The kicker: when the driver was speeding his way to the airport he was falling asleep at the wheel. On the highway I noticed the car was jerking occasionally. I thought it was, perhaps, a windy day and coupled with the speed he was having trouble staying on the road. The jerkiness made me more alert, and when I started paying attention to the drivers actions I could see: his eyes getting squinty, jerk of car, wide eyes. It was when he drifted and hit the rumble strip on the side of the highway that I officially began hoping that I would actually arrive.
Of all the time I’ve used this service I’ve only seen the one driver, so I am not sure if that’s why he is overtired. Nonetheless, I think it was inappropriate to put another human life in the car of a man who was clearly falling asleep. I guess that’s what a cheap ride (26 $ rather than 60 $) gets you to the airport. I’m not sure that I want to gamble with my life again for the sake of 34 $.
