If I pack the refillable mugs in my online bags will they be confiscated? I think I have done this in the past without an issue, but I woke up thinking about it. I can see someone in security having a bad day and deciding it would hold too much liquid, even though it would be empty.
Is the screener the only person that decides or could I ask for higher up?
