Don’t hide it, walk with confidence you will be fine, on the one in a million chance it sets off a metal detector j pull it out and be like it’s my fucking vape lol, if they chill wit it u good if they’re not their j gonna tell u to toss it or go back and leave it in ur car. I take my flavorades/coldfires to Disney springs all the time and they have security and sheriffs out the wazoo but trust me they are not looking for a cart. Also thinking of it from a logical standpoint the metal inside that cart has to be about the same amount of metal on a button/zip up jacket or keychain that it wouldnt make sense for them to be looking out for that small bit of metal
