What if you're cycling to a cafe for a slab of cake, or with a group who might have been exposed in italy? As already mentioned, social distancing is the best thing you can do. Not many who can really do this as intended though, as most of us require some human contact at some point or another. It's just a matter of time until it goes
endemic.
I understand the point you make and I don't underestimate the potential seriousness as outlined in your following post. Equally I could be a walker and face the same issues. Cycling is not relevant here.
In a modern society unless the country effectively shuts down social distancing is impossible. We simply have to eat.
I'm recently returned from Vietnam and Cambodia. On return I added a sanitizer hand gel to the gear I take with me. I will use this in a cafe. If the virus takes hold I will use the methods my wife and I used while in Asia. At any location where others might transmit a disease we wiped down all surfaces and hand santized afterwards. For example in a restaurant this would mean wiping our table area, cutlery, side plates etc. with sanitizing wipes. On an overnight train we wiped down every surface in the cabin. At no point did we use the useless masks we were offered everywhere.
I'm amused by how many people are offering advice that good hand hygiene is important. Isn't this what we should all practice every day?
A tale about this and an example of people's general lack of understanding of good hygiene.
One morning as I washed my hands in the hotel public toilets a Chinese man left a cubicle and walked straight out without washing his hands. I left and followed him to the restaurant. The first thing he did was walk to the coffee jug and pick it up. I wonder how much fecal debris he left on the handle for 100 other guests to enjoy??? He was of course wearing a mask to protect himself against Coronavirus!! Idiot would be a kind description.
