It might say face coverings but you can guarantee there'll be a few thousand people who are special and need ffp2 and ffp3 for their own special reasons and a guaranteed few hundred people willing to steal from hospitals or mug community care workers of theirs to sell to aforementioned special people.
Not to mention the fact that they are unsafe unless you've been trained in how to fit and wear them properly. It's almost impossible not to touch them to readjust them or try yo make them comfortable. Even I do it when it comes loose around the bridge of my nose or it steams my glasses up and but I'm in a care setting where I can immediately change my gloves, wash my hands and put on fresh gloves.
It's dangerous advise to give and we can't really be compared to cultures who are used to wearing them and therefore have plenty of stock and tend to touch them less frequently.
