No I don't, but I don't judge anybody who does wear one to make themselves feel more protected.
Although I must say, if you do wear them, make sure you're using them properly otherwise it is completely pointless.
Once you have you mask on you shouldn't touch it again until you plan to take it off, it should then either be disposed of or put onto a bag and washed straight away. The amount of people I see constantly touching their masks, moving them to scratch their face, or pulling them down under their chin is just ridiculous. Everytime you touch that mask you are potentially contaminating it and spreading germs around. And the people to use the same mask repeatedly that is kept in their car. Everytime you go out wearing it, it is getting contaminated, then you're putting it in your car, leaving it open to germs again, then putting it back on next time you shop.
And people that wear gloves in shops, completely unnecessary. Unless you are going to change them everytime you touch something different they are pointless. Everytime you touch something with your gloves on, the gloves are getting contaminated, you are then touching your trolley, your shopping, yourself, your phone, your purse etc and just moving the germs around. You are better off just using hand sanitiser regularly as you are going round the shop.
