But surely you are touching the food products with your gloves on?
I don't wear gloves, relying on the hand sanitizer, but I do disinfect anything we buy with plastic or metal surfaces. On natural and cardboard the virus doesn't tend to live that long(but I'll still usually give the cardboard a once over).
On masks - I can present to you the Southern States of the USA as evidence as to what happens when you return to something that looks like normal with a squint without mask wearing.
The UK is no doubt in a much better place right now, but the infections haven't gone away. All the evidence suggests that most Western world countries haven't got the stomach for proper social distancing, mask wearing or contact tracing. Without near zero infections at opening, you can guess where it heads and it takes weeks before you notice.
I've been wearing masks for a few months now. The best description I've seen someone use is that if places look like normal right now, you are best off avoiding them. Given my hyper cautious approach, you'll probably then be surprised to know I ventured down to Orlando 6 weeks ago - it was obvious that it would return based on life in general looking like normal, but the Disney/Universal areas had completely changed. Restaurants had lost half their tables, ALL staff and guests were wearing masks, hand sanitizer everywhere and verbally encouraged by staff. You kept your mask on when in a shop, but you could remove it at a table when eating/drinking in a restaurant. It all felt safer somehow, and thus far, in a State absolutely crushing the number one spot for infections since that visit, neither location has been linked with any outbreaks.
Life is not going to be normal for some time.
Even when you look at places that have seemingly got this well under control, like New Zealand - they are forcing people who travel there into quarantine hotels and then tracing their movements! That's fi you even manage to get there, as their borders pretty much remain closed. That's not normal by any stretch. Places like Australia, Hong Kong, South Korea, all keep springing places back into severe lock downs at the hint of outbreaks. This shit gonna be a bit crazy for a few months yet.
