Press the buttons along the right hand side from top to bottom in sequence. It usually works. Only failed me once at a station who was clearly intent on wild amenities and overkill experience.
I’ve done it, sometimes I buy coffee, use the bathroom, check email- and then I’m on the road again.
But that’s actually kind of a fun idea, watch a show or movie in bursts. Thanks! Maybe you look forward to the next charging stop, to find out what happens after the cliffhanger!
Yes, sometimes a really annoying ad will play on the video screen once you start pumping. Other times, they will show you a funny clip from a talk show -- it's still an ad but at least it's entertaining.
Most of the pumps I've interacted with have blank buttons near the display. In my region, the mute button is second down from the top right. Mash the unlabeled buttons though, and you'll probably find mute.
