When we arrived at McCarren and went to get the rental car, I initially thought \"hey, I made the right choice.  Look at these 5-6 people ahead of me in line while either one person or no one was at the other rental car sections all around\".  Not the case.  Why?  Later in the weekend I needed a car again, and went with Budget that time.  Budget's price was just as good as Dollar's, and Budget had nicer cars available.  Meanwhile, in this first experience, Dollar only had two people behind the counter.  I don't think I've ever waited in a 5-6 person line for soooooooooooooooo long.  It became painfully frustrating to the point that I considered trying to cancel the reservation on my smartphone and schedule a whole new one at one of the other car rental agencies there.  Not cool Dollar!
