Im sorry, that really sucks, what an end to your crusie.
At another airport, I watched someone take my bag off the carousel !!! My hubby thought I had lost the plot cause I took off after a random person, rather than look at the label, she actually started going through it to see if it was hers!!!!! I thought it was mine, then I seen it was definatly mine when she opened it up. I mean,come on. Dh thought I was bonkers till I explained!
Folk can be stupid!
Maybe the woman went through your suitcase to see if there were any valuables in it!
