Avoid shops near your home/work, you never know who's driving pass as you're walking inside.
Try to pick shops with a back entrance.
Keep sunnies, face masks in your car.

Don't forget to keep the evidence hidden digitally too.

use wechat to avoid any call backs from shops.
I have wechat installed on my phone, icon deleted but searchable when needed.

use a separate browser for using this forum (incognito mode)

you wouldn't want auto-complete to point to this website during a teams/zoom call when you're screensharing.
