Another old person here. At an office in Zurich I saw a layer of smoke filling the upper reaches of the atrium. I wondered how many working (i.e. smoking) hours it would take before it reached the balcony on which I was standing.

except for the dance bars. Dear lord the sweat smell during the transition was bizarre. It as always masked thanks to the smell of smoke. I think a lot places had to start thinking about adding nice parfumes, because almost at the end of that first year of zero tolerance inside bars, it was 'solved'.
