I've eaten some hamburgers at Krystal's that definitely overtook whatever else was in front. Some folks have had the same or similar effect from White Castle, although I never have. Chipotle on occasion moves things along rather briskly too. No fruit or green leaves in any of them.

It may be that it's not a digestion thing, but some other factor they have that accelerates the process.

Not a doctor but I know that some foods, in some guts, at some times can trigger a 'quick-release valve' of sorts. You're not digesting properly when that happens.
