PAX are required by law (law? or regulation? anyway...) to place all 'liquid' toiletry items (even if they gels or solid) in a closed bag of a certain size.
I do that. I also carry extra ziploc-type bags in case the bag in use breaks or rips.
Preparing to return from Paris recently through Calgary (don't ask) I used one of these ziploc spare bags to hold cosmetics and makeup I had purchased.
Departing Calgary, I was put through a 'bag search' in a private cubicle (my request). The agent amateurishly pulled everything out of the bag in a jumble including the regulation small bottle/liquid in bag--and when she came to my second ziploc bag holding only lipsticks and powders etc, she said 'You're not supposed to use those bags except for liquid." I never make any response to these agents. She found nothing of interest in my bag, so I began to repack it.
Is this so? Yes, I know, it's required to put all liquids in a ziploc bag.
But--is there also a second unspoken regulation--'don't use ziploc bags for anything else' or 'don't use ziplocs for other purposes'? Surely this cannot be correct.
Observations please.
Sounds like another highly trained TSO making up rules as they go.
I use an extra ziplock to put the change and other small items I have in my pockets then place that into my carry on. Never a question about doing that.
