All locked up!

Sad when supermarkets have to take this kind of action.  All the spirit drinks are "behind bars" to prevent them from being stolen.  If you want to buy gin or whisky etc you press a button on the cabinet and a member of staff will come and open the cabinet.  What happens next?  I don't know whether or not they will have enough staff to do this once the Christmas rush really starts.  What a shame we are reduced to this!
