I'd definitely be the annoying shit on that one. I would insist on proper PPE for the environment. If the smokers in the team want to handle it without PPE, that's entirely on them.

It's also worth noting the smoking rooms are effectively empty, except for lights and some seats. Most staff can avoid it entirely.

Have the employees who smoke work the smoking section. Let us light up with the customers we serve! /s

Edit: I like @Cynar's idea too. Full respiratory gear like a firefighter. lol
