During a recent trip to Las Vegas we had two very negative experiences with this bus system.
A driver pulled away from the start of the 108 route at the airport even though he clearly saw a woman waving and approaching the bus. She was no more than six feet away from the door of the bus. But, he ignored her and left.
Four days later we planned to take a bus to the airport on that same 108 route from an intersection which was a scheduled stop. We waved as the bus approached but the driver ignored us and passed us by. That scheduled stop intersection has no bus stop sign posted so we walked two long blocks to the south at an intersection with a posted bus stop sign and waited for the next bus. After it was already 15 minutes late we gave up and hailed a cab so that we would not miss our flight.
