The whole thing after 17 years experience with "midnight shoppers" is the more you can do to either slow them down, make it louder to "shop" or to encourage them to move to a easier "midnight store" the better.
There is no way to 100% keeping the "midnight shoppers" out if they really want something but the more you can do to discourage their "shopping habits" the better.
