Yellow Cab saved our early morning flight to the Bahamas for our wedding. Already being stressed out about the wedding, the last thing we needed was for Discount Cab to blow off our website made reservation (AND we talked to them on the phone to confirm). Discount chose not to call us when they "couldn't find us" and left for an new fare. While dicking around with them, I called Yellow Cab and the were there in 15 minutes.
Driver was friendly and did a great job at sensing our eagerness to get to the airport (as now it is about 30 minutes later than our original pick up time with Discount!). He didn't gripe about how many suitcases we had and was beyond courteous and polite.
We will call Yellow Cab again before we ever call Discount.
