Can you smoke? Just on rooftop?

I don't think so, not even on the rooftop.

I wrk there n yes u can smoke on the roof top just don't dump ashes everywhere n anywhere I will give u an ashtray n thts 4 tobacco products n ⛽ n don't leave them cigar guts everywhere ask for AP thts me

Unless there's no one there or your vaping light that's gonna be a hard no on the rooftop sadly.
