If a driver really thinks something funny is going on, it wouldn't be delivered to your door by your usual driver. It would be delivered by an undercover narcotics officer if what you ordered was, indeed, a problem. As long as it's your usual driver, not some different-looking individual insisting you sign for a package that doesn't require a signature, and it's in a prescription bottle, or not a tightly-controlled substance, then you're OK. There is NOTHING the DEA can do at this point in regards to people establishing a doctor-patient relationship online. Whatever the normal driver(s) seem to be thinking, it's of no consequence to you. People will always be nosey. I say to heck with worrying about the driver. Instead, I'd be more concerned about the place(s) you order from delivering as promised. JMO.
