At least in US airports, not only must all the liquids, gels, and aerosols be within 100ml containers, but these 100ml containers must all themselves be contained in a single clear zip-top plastic bag per passenger of no more than 1 liter in volume.

So, technically, TSA is not being maximally strict in enforcing their rules when they allow any sandwich containing even tiny amounts of liquids like olive oil or gels like mayonnaise to enter outside the single 1 liter bag per person that also contains their shampoo and toothpaste. No, I don’t expect TSA ever to enforce this maximally strict interpretation, but that is how the rule is worded.

By contrast, some foreign airports that mention the 100ml rule make no mention of the single 1 liter (using the non-US spelling of liter) maximum enclosing container volume per passenger, let alone the requirements for the enclosing container to be a clear, zip-top, plastic bag. So this particular absurd pedantry about an absurdly worded rule that’s designed for TSA to keep you guessing on each screening about with how much leniency they choose to grace you that time does not apply to most foreign airports.

That's the theory. In practice, enforcement of the zip-top plastic bag rule is next to non-existent.
