In Sep 2016 I was on a South of Spain cruise out of Southhampton. Almost the entire passenger list was British; so a couple thousand Brits and less than a couple hundred Yanks. I liked the steak and kidney pie, regret passing up the bubble and squeak, really loved the British breakfasts (especially the British bacon; I didn't try the pudding though), didn't dare try the Vegemite. The last-night party was a celebration of British popular music (featuring Beatles and Stones, of course) for which the concourse (an "atrium" that ran the length of the ship -- yes, the inboard cabins had that as their view) was packed; they closed with Monty Python's "Lighter Side of Life" for which everyone held his/her lit cigarette lighter high.
The Brits kept needling us about Trump and we kept needling them about Brexit. Neither side had any explanation for their own national insanity.
