Only put one on twice due to the rules to visit my Mama in the dementia care home so I could visit her, right at the beginning of the BS pandemic, no mask, no entry...removed it as soon as I got to her room. Haven't worn one since....got abused a few times in the supermarket for not wearing one...my local supermarket starting giving out mask exemption stickers to those with an exemption to wear whilst shopping when too many people complained about being abused by the nutters lol
