I have only done it once, and got some evil looks from the others queuing. It was my only day off and was knackered and needed some essentials so thought 'just this once'-might not do it again!
It sort of felt like all the clapping in the world and rainbows doesn't mean much in the real world, but I might be a bit more careful about waving my lanyard around in the future (and yes, i'm frontline ward NHS staff working on covid wards fwiw).
Any thoughts from others very welcome.
