I’d quite forgotten. It happened while crossing the Bay Bridge on the way to San Francisco airport. That was nearly two months ago now. We were lining up to pay the bridge toll. A car in the next lane asked to get in our lane and go ahead of us. We indicated to let the vehicle in. When it came our turn to pay the toll there was no charge. The car ahead had paid.
Yes, I’d quite forgotten this event. Thank you stranger.
