Hi Mike I'm happy to send you a few quid on pay pal not looking for something for nothing. Will PM

I have PM'd a reply. No charge for anyone supporting the same means of promoting public health and well-being: "We are all in this together"

I started making smiley badges yesterday:

I will wear one and carry a few loose in my pocket for anyone who shows interest. Other suggestions for wording are welcome.

Stickers arrived many thanks to Mike Austin these will be put to good use in prominent locations!

I found another place to put these stickers (without causing myself physical discomfort). Letters and parcels offer free advertising space. Paper stickers are adequate - or printing direct to envelope even.
I wear one of my badges (like my avatar) and pin another to my bag ('protect the few - free many'). I have not seen anyone else wearing smileys and I have only had one person ask for one.
If lockdown sceptics are to group together and be effective, they first need to recognise how many others share their views. Few are confident enough to take any action in small numbers.
