This keeps happening to me. Arrive at a pelican/ puffin crossing where two or three people (or more) are already waiting on my side. Stand behind them assuming (as surely always used to be the case!) that they have pressed the button and the lights are about to change. Look at my phone.
Time passes.
The lights never change. They seem unconcerned by this. They look at their phones.
Sometimes I say loudly 'oh dear me, did no one think to press the button' in a middle-aged way.
Usually I edge over and press it.
Is not touching the button a post-Covid thing?
And what happens to these people if a button jabber doesn't show up?!
