Man, broken EV chargers are such a pain. Reminds me of the time I was stuck at a mall with a dead phone and all the charging stations were busted. Self-checkouts are no better, always have that one item that won't scan. Yeah, it's like they set these things up but forget to maintain them.
Carry a portable battery pack for your phone, saved me more than once. For EV chargers, check the app reviews before you go to see which ones actually work.
