in the light of what you describe, I think you acted responsibly, and that in this case you acted as a stop to a possible slip through Reason's "Swiss Cheese Model"



Someone else should have done it for you before you had to bring the matter to the attention of the crew. We don't know enough about of all the process that brough that particular passenger sitting next to you, but luckily it was you and not some other passenger with not enough experience to realise. And surely it must have been an uncomfortable situation for you, having to be very careful on what you said in order to let the crew understand your motives.
If you have the time, I suggest that you write to the airline in question about it.
