We were treated like *********

I went to Woolworths on the 16 January 2015. As we worked in the store were had a security lady that followed us from one section to another section. Enventually came a very big security man who told other customer to look after their bags and cellphones. I then realised that the man is warning the customer to be careful of us (Us-Myelf and 3 friends). We were very offended and told the manager at the till as we were paying but the manager was not much help.
