We called Yellow Checker Saturday night an hour and a half before the start of a concert. We were told by the dispatcher that the driver would be at the house in 20 minutes. Perfect! After 30 minutes I called the dispatcher line again. Apparently the driver picked up on the way to our house and was only 10 minutes away. Irritated that we missed the opening act but with enough time to spare before the main event, we agreed to wait another 10 minutes. After 15 minutes and quickly approaching show time, I ended up driving us. We couldn't have been more disappointed as I ended up having to leave my car overnight and pick it up the next morning. Don't waste your time.
