Don't use this trolly

Its a very nice checkers at menlyn to shop at, but unfortunately the experience was ruined once I wanted to leave with a certain trolly. I did my monthly grocery shopping there, so had many parcels, just to be told by security I can't leave with the trolly. I rep**** how must I carry all these items then. The security was very rude replying to take the other type of trolly. Now I have to move all my items and parcels to another trolly, how ridicules is that. If the can only put up a sign when entering regarding these trollies, not just at the exit. These shops really need to get there security also under control, the rudeness could loose them business. They have lost mine.
