I've had this one too - Colgate tube marked "110g", the packaging has since been redone to "90ml". I thought it was self-evident that a measure of weight is not the same as a measure of volume - apparently not.I had some deadly toothpaste taken off me because the little bottle it was in said "140g" on it. I pointed out that was grams, not mL, and that toothpaste is probably a lot heavier than water but my pleas met deaf ears.
Later on I measured a similar bottle to be about 90mL.
The dumbest one was half a roll of electrical tape, "because you could restrain people". If I hadn't been so annoyed I would've been chuffed that the guy thought I'm some super powered ninja able to restrain a plane-load of people with a few metres of pvc tape.
