Australind Shopping Centre

I shop down at the shopping centre regularly and on Saturday the 17th of Dec 2016 at around 1pm, my partner, my Grandson and myself left the shopping centre and my Grandson had his scooter parked behind the large planter near the entrance to the shopping centre, as he always parks it there so 1 it won't be stolen from outside and 2 he knows that he is not to ride it inside. When leaving the shopping Centre the Security Guard without saying please said don't bring it in here again, I told the guard that he parks it up at the planter and she said I don't care and I said it is a $500 scooter and I don't want it left outside. The guard started ranting and raving and was very very rude to myself and my partner and raising her voice for the whole entire shopping centre to hear.
I found her behaver very aggressive and offensive, after I walked of she said to people around her did you hear her she is trying to take my job away.
I am going to ring the security company she works for and make a complaint and would wish that your Management would do the same or at least look into the matter.
If in future my Grandson does take his scooter with him I will be putting it in a shopping trolley and taking it around why I do my shopping. You must review your entry signs because they are not written well enough.
Thanking You
