A couple of years ago the gas pumps at station nearest to my place were replaced by devices with screens that play ads with sound - so far just touting discounts with their supermarket loyalty cards. They start when someone picks up the nozzle, and were annoyingly loud initially; the sound has been turned down a bit lately.

(Well, there's another reason for me to be pleased with having traded one of the family cars for an electric that charges at home ...)
