No power is different than no internet, so that was different. We were a 24/7 store (7-Eleven) and sometimes we would close if it was a prolonged power outage. No one has 100% uptime, not even 24 hour gas stations.

They used to have a crank!

please be more respectful to the manager of that establishment!

He said "offline" not "no power".

Also, fuel station can probably successfully run it's own backup power;)

They don’t, at least not here in the US. In areas with power outages, gasoline stations do not operate.
