I have been wearing them in shops for around a month or slightly longer now and I would say it's one in 15 wearing them and bizarrely I have only seen one shop worker wear any sort of face covering and he was Italian. Oddly I did spot one till operator wearing fingerless gloves! Again though people on here and in the media moaning about why the government wasn't telling us to wear a face covering and when eventually they suggest wearing them in shops and other indoor settings, hardly anyone does.
