I saw that plenty of times when the £ was close to 70. There's no upper age limit, either.
Back in 2009 I was sitting with a couple of German guys outside a small bar at VT1. We were discussing Canada's massive oil and gas reserves when the British codger found his long awaited segway into our conversation.
"You had enough gas to kill the f ing Jews, didn't ya?" Screaming at the top of his lungs with a horrible accent. One of the Germans was a cop who didn't drink. His reply was "be quiet old man, drink your alcohol and talk to your prostitute ". That kicked things off, but thankfully the 40 year old Germans didn't beat up pensioners so the old clown made quite a show before his prostitute dragged him indoors. The £ was falling and the poor guy was being forced back to a council flat in beautiful, balmy, blighty.
