Makro Cape Gate frustrates with treating customers like *********

So you buy a trolley full of stuff at Makro, then you walk two meters to the exit and a security guard wants to search your whole trolley, and tick off every item you have just paid for. This is really frustrating because 1) you feel like a ******** 2) you suspect you are being inconvenienced because they do not trust their own personnel 3) it is a real waste of time. Sad to say I lost my sense of humour with a security guard this weekend at Makro Gape Gate because of this frustration, while I know the guards are only doing their jobs. I still need to apologise to the guard. The thing is, the job they are doing is frustrating customers who have to stand in line to be searched after just purchasing items that are each individually scanned and checked by the person at the till. One has to wonder, if you just bought the stuff, is it not your property, and could you not refuse the intrusive, time-consuming and highly frustrating checking? Secondly, could Makro not ensure that all the checking that is necessary is done right at the till instead of treating customers like *********?
