Almost missed flight.
Driver parked one street over and sat until I started dragging my suitcase over, even though it was at the end of the time window they had given me. Driver then took longest way to next stop, where the person spent overt 5 minutes in the house before finally emerging. At next stop driver stood and watched for about 10 minutes while 3 members of a family got in van, got out, went in house, got in and out of car, got more luggage, and finally after about 10 minutes got in the van with a fourth person. I let everyone know I had the earliest flight, that I was going to miss it if we didn't get moving. If the line at the check-in counter or security stations had been any longer, I would have missed the flight--and there were 2 small grandchildren waiting to join me at the airport.
