Many moons ago, there was in a train restaurant car this legal attorney, who kept on making phone calls in those public premises. No speaker, but his own part was loud.
At one stage he was talking to his client. It was about some long-standing legal dispute, and the attorney was not at all optimistic about their success. But his plan was for them two to go see the other part one more time that same day and make one Hail Mary pass kind final threatening bluff. If this would not make it, they would bow out from the matter.
Names etc. were mentioned. Did I say it all was very loud? You could not help hearing and being disturbed.
After several decades, I still regret I didn’t go to the next railcar, find out the other part’s phone number and give him a call.
