Getting treated like a ********

I went to do my weekly shopping, bought something somewhere so I gave it to the officer at the door, I wanted to proceed and they told me helmets are not allowed in the store and forcefully wanted to take my helmet from me. Where are the signs? When did the rule starts? YOU LEAVE THINGS AT YOUR OWN RISK! AT THE DOOR, I didnt agree with the premature rule that just came now because the security officer is new in the store and want to shine and show authority, because if my R5000 helmet fall in their hands it will be my responsibility to buy a new one, or worse I found out the hard way, I am involved in an accident and I get injured cause the helmet already been damaged.<br> <br> I said NO, I will hold my helmet and proceeded to do my shopping, now they come 5 of them trying to pick a fight with me, telling me how I am going to ***** and put thing in the helmet, yet there is a guy next to me holding a bag and the sensors at the door works properly. How do you react to such accusations as a customer when employees and security officers act like owners of the store? Telling me they going to tell their cashiers not to help me and I am getting into their shops and making my own rules?
