So today while my wife was in town, supercharging, I got a notice on my phone that she was parked with charging complete and fees had been started. She ran out of data on her phone so didn't get the notice. I'm at work, but luckily I could move up the charge limit from 80 to 100% so she had time to finish shopping and get back. It takes 65% to get home from the nearest supercharger in our MX 100d so we usually don't fully charge (95% charge to do it in the winter - 6 months of the year) , and get home a lot with 4-7%. Not this time! But I thought that was a good just-in-case trick for when our schedule runs behind.
