When Sue still had some hearing we were standing at a Heathrow departure gate watching my father queuing for the metal detector. Pa had a brief chat with an elderly couple and then spoke with a security guard. That guard then went to speak with a colleague, at which point Sue said there was going to be a problem. She’d seen the first guard tell his colleague “we’ll teach this ********* clever ******* to tell us our jobs”.
Pa was then put through all sorts of extra questions and checks taking about 30 minutes. I asked another guard what was going on, his reply was very unfriendly, to say the least.
