I got a job but I need training

At security for a domestic flight my 60 ml travel shaving cream which I fly on international flights with was confiscated by security staff because they decided that they did not like the MSDS symbols on the canister yet it is below the maximum 100ml limit at 60 ml and also sold at Dischem as a travel size aerosol. Nowhere is their gripe listed on the prohibited items list and this is just another incident of *********** idiots making their own rules on the trot.

Well done ACSA. Train your stooges or show me where my confiscated shaving cream is prohibited in hand luggage on domestic flights.
