Some of us can remember smoking...Look at the infographic in the link I posted. Even if you were staying socially distant the vapours will disperse throughout the building unless it's very well ventilated.
Sitting in the "non-smoking" area didn't make a lot of difference.
Even outdoors, exhaled aerosols are detectable many yards away - they're even visible now, from the vapers...
