Every Remembrance Sunday and Nov 11th, when I worked at retail, we did a tannoy announcement with 5 min, 2 min before to inform customers that the store will be observing the 2 min silence. Then another to start it.
Every time there were customers who kept talking. Plus one time a woman in her 50s shouted “why can’t anyone serve me some fucking fags?” Everyone just looked at her. Some had the courage to say how disrespectful she was once the silence ended.
If you are unable or refuse to observe the silence at 11am today or tomorrow, please don’t be in a public place.
