Don't understand there security

There security is the pits!! I got wanted to enter with a packet from another store but wasn't allowed. They wanted me to give it in at the window despite it being a see through packet. There is no why I am leaving my other purchased items with them. In the past I never had this. I turned around and went to the Spar close by. Time to get with the times.

This was at Northcliff Piazza
