One day on my way home from work, I stopped by white castle because I was craving some chicken rings and ranch sauce.
Not even 10 p.m., pull up to the drive thru, and the bish tells me they're closed?? WTF? The place is open 24 hours!! But alas, instead of b*tching and moaning like you did, I just left because I was in no mood to argue with a bunch of idiotic high school dropouts.
10 minutes before closing is negligible, I know when I'm closing that I hate it when people come in 5 minutes before we are supposed to close, they d*ck around in the store for 15 minutes (after we close), and then proceed to only buy $4 worth of stuff.
