I don't expect a location to go against their policies, but for a facility to have an outdoor NON-SMOKING section where non-smokers can go outside and re-enter yet not allow a smoker to exit/re-enter the building or offer an area to smoke is about the biggest slap in the face a business can make.
If you only want a non-smoking clientele then perhaps you should say so up front. Politically correct discrimination at it's finest .
