Private guards on the spot over lax screening

What should normally happen when you walk through a security check-point at the entrance to a supermarket, hotel or bank? You remove your phone and keys and place them on the side but in your pockets, you have a few coins which you didn't declare; and then you walk through the metal detector frame, then the device screams but the guard is unbothered.
