I called this cab service from a hotel that was not my own and they were very prompt. Unfortunately I needed a ride to an urgent care (for a non-alcohol related situation- boring, i know!). After I was dropped off, John gave me his card and told me to call him when I was about to leave, so I wouldn't have to wait in the cold. Turns out that the urgent care we went to didn't take my insurance, so John turned right around, picked me up and took me to one that did. He ended up driving from that urgent care, to a pharmacy for my prescription (then gave me a bottle of water after seeing i forgot to buy one). Then we swung by my hotel and went to the airport.
I cannot even begin to express how amazing this cab company and John are. John was very pleasant- even as I got frustrated and teared up with the whole situation he kept his cool and made sure I got to where I needed to be.
I will always use this cab service in Vegas and I hope you do too!
