I think people don’t understand the difference between a point, a service game, a set, and a match. One point isn’t crazy. She could just double fault or she can miss hit it. Serena had 56 unforced errors in one match against Wang Qiang. On her bad days, this is definitely possible. However, a service game is extremely unlikely. Winning a service game is what is needed to get on the scoreboard. I think the question is most likely poorly worded and means a service game.
That being said, it is crazy if a person with no or little tennis experience thinks they can get a point off of her without her actually making a mistake.
I use fastmail. I have used it for couple of years now and it has been working well. It was a calendar, notes and file functions too. Tried proton. The app was always slow to open and refresh. It is also easier for people to understand fastmail.com when you are giving them your email.
