Ok then after consumption will the customer be driving?  I do see where Assemblyman Constant is coming from but as far as I know, please correct me if I'm wrong, there still isn't a measureable point of impairment with marijuana.  Yes, people drink in restaurants and bars and then can transport themselves legally if below a measureable amount.  I don't think any such ordinance should be considered until it can be determined at what level someone is impaired.
