Smoking's a tough one, Dev. At my house, we have a rule, no smoking indoors, but people can smoke on either of two patios. We ask that they take an ashtray with them and dispose of the butts themselves when they come in, and wash the ashtray when they are done.
As a closet smoker myself who has quit many times and found it hard even though the past many years I hardly smoke at all, I know how hard it is and I think I'd deal with one problem at a time.
But you know, it`s your house and your boundaries to make. And if you and Mr. Dev don`t like any smoking on your property, it`s your right to call the shot.
How is that for a wishy washy answer
`Maybe` is my final answer, Regis.
