In my experience, I never had a single time where the charging got interrupted nor have I had any other kind of other failure to charge properly on my car.
I live in LA where chargers are very used so it's probably just a matter of the locale you're in.
I've had chargers fail at:
* EVGo at Warner Center
* The greenlots at The LADWP on Ventura and Corbin(ish)
* Flo at reseda and oxnard
* Blink or whatever at Kaiser and DeSoto
* Blink at the Ikea and burbank
To name a few. Tons more floating around in my head between my two EVs. Every single one of them likes to fail at some arbitrary time when I'm far away from my car
