you know what i used to do that really got them upset. the night before a trip i'd make soup to take along. well i froze it in an average container (alot bigger than 3oz) and would take it with me. every time i went through security they tried to take it from me and i made it a point that is wasn't a liquid or a gel. after a few times talking with the supervisor he kindly asked me to stop, so now i make sure i'm in uniform everytime i go through with it.
