@freemo @DemocracyMattersALot let me guess you were wearing shield protectors and ffp3 mask?
That's way beyond what an average teenager will wear. The average teenager, if forced, will wear ffp2 masks (because these are the most common) and ... probably the same multiple times.
No, it's not "my fault" if I am an average person that buys an average mask from an average shop. People with covid symptoms should just wear a mask.
