Hmmm...I think you raise some valid points (non-smoking and smoking rooms SHOULD be a guarantee, not a request), but your analogy here does not hold well with me.
There simply is no way of getting around the bottom-line truth that second-hand smoke is dangerous to people who might be following you in that room. More and more studies support the theory that second-hand smoke causes cancer, but even that issue aside...my mom's throat closes up when she is in an enclosed space with smoke (stale or otherwise). She is EXTREMELY allergic.
I don't think I have ever heard of anyone having allergy or asthma issues (or, for that matter ANY kind of issues) because someone ate in their room...and, this includes shellfish and peanuts...two of the worst allergies ever!!
Smokers just need to accept that the choice of what they do with their bodies ceases to be only their concern every time they exhale, or even allow a cigarette to burn. Dangerous toxins are released into the air and can do damage to others. Non-smokers are not trying to limit your personal freedoms, we are just trying to keep as many dangers away from ourselves and our children as possible. If you could assure me that your smoking in a room could all be "cleaned up" by housekeeping (much the way a messy room can be cleaned), I would say "smoke away". But, sleeping in a room that you have smoked in would send my mom to the hospital and ruin all of our vacations. How fair is that?
