I'd even support a situation where visitors to a business could sign a waiver saying they agree to have chemical residue exposure as a condition of entry. I'm not against smoking. I am against having smoke applied nonconsensually.

What is the difference between signing a "waiver" and voluntarily entering the business? (Besides a lawyer getting $$$)

By entering the building, then remaining when the ashtrays and/or any other evidence of smoking being allowed are noticed, the customer has given implied consent.

Because they are accepting risk, so a waiver is appropriate.
