I believe sestra mentioned this helpful comment before, a few months ago; If the website says it's open, it's OPEN for the lighting audit. During the last round of Mobil audits, I encountered a location that was obviously CLOSED. Pitch black, no lights at all, pumps not operable. BUT corporate website says they're open 24 hours. I completed the audit with all the infractions noted. Shop was ACCEPTED and paid. However, about a month later, I received an email stating the shop was EXCLUDED but I can keep payment. That's the MSC problem, not mine. I should be thankful they didn't claw back payment?
Just take a lot of photos for back up when they claim you missed an infraction. For Mobil, I think there was a comment box where I noted the website saying 24hrs. I've noticed the current Bp doesn't have a comment box.
