When they forget the ketchup... but still charge you for it.

You know it's a horror story when they hand you your bag, and you're excited about your meal - until you realize they didn't give you the ketchup packets you definitely paid for. It’s like they think we don’t need it, like we’re some kind of sauce-less, dry potato-eating aliens. "Nah, you're good, bro!" Yeah, sure, until I’m drowning in sad, naked fries!
