I am pretty passive aggressive.
Two weeks ago in the business class cabin of a train in Italy, maybe 10 people in the cabin. First guy has a 5-10 minute conversation on speaker at far end of the cabin; little bit of yelling. No kidding- 1 min after he shuts up the guy across the aisle pulls out his iPad and starts watching a talk show of some sort on speaker.
I loaded up some NWA and enjoyed F the police at a high volume for all 4 min or whatever.
There was not another sound the next 1.5 hours of the ride.
I will I’ll be deploying this at every opportunity.
