No trolleys allowed in a store?!?!?!

Today I experienced absolute humiliation when I was asked to leave your Walmer Park, PE store because I had a trolley, and apparently trolleys aren’t allowed in the store (I must admit that I didn’t see any signs stating this, especially not at the entrance). I’d like to point out that my 2 year old son was sitting in the trolley. I didn’t have his stroller with me, so this was my next best option. I was willing to spend a substantial amount of money in your store until I was told that I could not be in there with a trolley. What was I to do with my son then? Let him run around while I looked through the racks? Leave him at the door? Not a chance!!! There were no other bags in my trolley, leaving it empty for anyone to see what was put in there. I’ve been allowed in the store with my twin pram, which is bigger than the trolley I was using AND has a well-hidden basket underneath. I’d also like to point out that your store is situated in a mall...where people use trolleys!!! Note, also, that your store has a children’s section. SO many mothers use trolleys to get there little ones around. So please explain to me why a good-paying customer was asked to leave over something so stupid?! I’ve posted this all over Facebook and have had a lot of friends complaining about the same humiliating treatment. I expect this STUPID rule to be removed!
