I dont think the o p is saying theyve to drive wearing a mask, just to wear it to their door.(eazybee-you cant drive with a mask on if you wear glasses as they steam up!) But, my youngest son is CEV so we take extra care- but some deliveries (most)drivers are not wearing masks, they do stand back, and me & elder son wear masks, to bring in shopping, youngest stays in his room well out of the way,we dettol wipe all shopping and we are fine so far.As drivers don't come in its a minor risk I'd say.Had some washer fitters come, they had no masks, but did have gloves.i wore a mask but left them to fit washer.went back when they'd gone, had left front door open etc,sprayed dettol in the air etc..Most do comply, if they've to come in, maybe those 2 were 'exempt'? But all ok anyway.
