I had a lock/zip/strap ripped off of my bag on my last trip, I know someone was in my bag as it wasnt how I packed it and the bag is now unusable. OK, so the bag is a couple of years old now and nothing was taken, but it was a sturdy canvas fisherman/offshore holdal which wasnt cheap.....should have lasted a couple more years at least.
.......Naturally I didnt notice until I was at home and tried to open it using the non-existant zip....
So who do you complain to?
Its like the rest of the security bull**** - put up and shut up...
