Offer you one and then fine you. Seriously, don't forget and if you're forgetful then prepare early

I have one in my car, a spare in my backpack, keep one in my jacket pocket, and a cheap disposable in my wallet folded up. That way if I forget, I'll have one.

My city in Australia had a grace period for everyone to get a mask. After that a lot of fines were handed out.

Without fines I doubt we'd have seen compliance anywhere near as high because there are a lot of people who don't want to wear them but do because they fear the fine.

There's also a social tipping point sort of thing that happens, and fines help with that.

When hardly anyone is wearing a mask you feel a bit weird or silly.

When half the people are wearing masks you look at the people who are and aren't and can't help but wonder which side is your in-group.

When fines are enforced, everyone has an "excuse" to wear a mask. Darn fines.

Then, when everyone is wearing a mask you feel naked if you don't have one. Only the seriously anti-social will defect.
