I took Flixbus from Inverness to Glasgow on 18/09 at 12:50 pm. Half way, the driver left the bus and the bus was waiting for something. I saw another bus before us, and thought we were in a traffic. 10 minutes later, someone came back and another driver boarded on. I asked if there was a shop I could go buy drinks. He said no. It just finished. It all means the first driver should have told us what the stop was for so that the needy passengers can have a chance to go out buying whatever needed. The second driver was rude. He said if you wanted to eat something, you should have brought something from Inverness. I said I did. But I just wanted some water. Recommendation: drivers should be customer service oriented! Tell us if you give us a chance to stretch leggs out side or to buy something. We are humans and need something sometime unexpectedly for health reasons.
