Reminds me of the time I had the opposite happen. I went to a mcDonalds around 11:15 pm for some late night munchies. I didn't know this particular store's hours but as I pulled up I saw people inside and all the lights were on. The Drive thru menu was lit up too. I drove past the front door slowly on my way to the drive thru, trying to see their store hours. None posted. So I pull into the drive thru and wait at the speaker. After 2 minutes and no one saying anything I ask "Hello? Hello?" Still nothing. By this time someone else had pulled up behind me in the drive thru. I wait another couple minutes at the speaker before pulling forward to see what's going on. As I approach the payment window I see there's a lady in a mcdonalds uniform standing behind the counter, and apparently she knew I was there and was ready for me to pull around because she was already yelling "We're closed!" at me.

That mcdonalds has been there for decades and to this day it still doesn't have its hours posted anywhere. Blows my mind.
