I do not mind cigaret smoke. The only reason that I will not allow it in either the taxi or the UberX car is not because of gubbamint regguhlayshinn, but, because customers do not like the residual smell thereof. I have a major problem with the gubbamint's micromanaging my business. I have no problem with the dictates of market forces, even if I neither understand nor agree with them. The customer wants what he wants. The only major corporation that I have seen that ever got away with telling a customer what he wants is Icky-D's; yet even now, as well as from time-to-time, even they have or have had their woes.
Sadly, passengers who have been smoking just before they board the vehicle tend to drag the smell of the cigaret into the car with them. I would be hard put to get away with refusing the transport, especially in the taxi, as they would not be smoking while they are on board the vehicle. Uber's rules about refusing a transport are a bit more loose, but, refuse enough users upon arrival and see how long you remain onboard.
The Ozium is a rather popular solution, although I have yet to try it. There is a Wally World about one mile from my home, and I understand that Wally World does sell it. Glade does seem to work, given time to work and dissipate. I did have a customer once complain to Uber about a previous rider's smoke smell that he dragged in with him.
While I understand that the law both in New Orleans and Louisiana, in general, is a bit more loose about open containers, here, its mere presence in the vehicle, regardless of in whose possession it is, earns nine points for the driver and three hundred dollars for the City. Even a long empty beer can that someone stuffed under the seat can render unto the driver the above mentioned penalty if it is the wrong driver in the wrong place at the wrong time pulled over by the wrong police who is in the wrong place at the wrong time and subsequently drags the driver before the wrong judge at the wrong time.
