I'm sure I've seen security staff chase down and frog match shoplifters in to a back room, kept them contained whilst waiting for the police.Security staff can't do nothing, they have no powers.
I used to manage a pawnbroking shop and had security down nearly every day for something, all they would do is try and talk to the person causing trouble, if it kicks off then police are called.
Even the presence of someone in a uniform at the door giving verbal advice will act as a deterrent to all but the most determined anti masker.
