Carry on as normal, dropped the mask completely . The only thing I tend to do is keep out of any small shops that seem to be stuffy. The only big store I stop out of, but there again don't find much call to go into anyhow is Sports Direct, it always seems to be hot and stuffy in there, very little air circulation, if any, buts thats the one local to me, may be different in other places. We have two local ones, one on a retail park, the other in the main town shopping centre, both are the same.
