Recently at a U.K. airport we were flying through with our young child. His food and liquids were all in the correct bags and were all less than 100ml. They insisted in taking every single item out, x raying and residue checks on each.. touching them and putting them in dirty trays in the process (bear in mind he will be holding packets later, yum). When we pointed out they were all compliant and under 100ml we were made to feel like disruptive passengers. One item (still under 100ml) “failed” so she unfortunately had to go and find her supervisor to see if it as allowed through or not... disappearing for 10 minutes.
We are crew and know how the game works. Some workers are just up for a fight. Power trip?
