Theft from booked-in baggage

I returned to Johannesburg from Cape Town yesterday on flight JE166. When in Cape Town I bought 7 bottles of special chocolate cookies from a chocolatier in Cape Town to present as gifts. I checked in my bag in Cape Town and when I opened it up last night on my return, to my disgust I found that my bag has been carefully opened, one of the bottles neatly opened and half of the cookies ****** and the bottle then placed back into my bag!<br> <br> I find this behaviour by the airport staff absolutely disgusting and of the lowest form of life. The fact that someone took it onto themselves to believe that they have the right to open somebody else's bag and take whatever they want from it is bad enough but I feel even worse by the thought that a stranger ruffled through my private belongings.
