Edith, in Ohio a cab would be considered a workplace and smoking would not be allowed by law. If reported the cab company would be fined. Hit them hard in the wallet until it is corrected.
I remember how peeved I was when Ohio passed a few years ago the prohibitive indoor smoking laws.
Now as a nonsmoker I see why it passed. I watch people smoke now and it just does not look natural.
Jennifer, looks like you got a week in, good going keep it up
