No moms allowed

I visited Zara in Cresta Shopping Centre this past week. I had my 14 month old son with me in a clean,empty grey Woolworths trolley. He started walking and does not want to sit in his pram anymore. But enjoys trips in the trolley. I stepped into Zara and at the door they told me that trolleys are not allowed. I then asked,what must I do. Because my son does not want to be held,he will run around in Zara causing chaos and I won't be able to shop at all. They said it is Zara policy. I then asked for a reason but they could not provide one. I had no bags in my trolley,so there were no risk that I could ***** something and hide it in my shopping bags. So,why can't I take my son and the trolley inside? If moms with little ones does not "fit into the Zara image" why do you then have a baby and children section in your store? I am very dissapointed and will never visit a Zara store ever again. Well,I won't be allowed. Thanks for discriminating against moms!
