I am grinning too cos I think we've met the same "sturdy" lady!!............
we flew to Oz in December & my hubby's 40th was during the flight.
Emirates sang Happy Birthday to him & gave him a cake which was then packed away in a box.
Going through customs took AGES & just as the sliding doors were in sight,we were stopped by said customs woman..
"have you any FOOD?" she barked...."Er,no " I replied,I had completely forgotton about the cake,now balancing on top of the suitcases with a sniffer dog digging his way into it!!
I then went into this dithering,giggly,nervous mode when you think you're about to be arrested....trying to explain that it was OH birthday,kind peeps had given us cake,blah blah
and she shouted back
"well it sound like FOOD to me!"
and waved us through...........
She was about 3ft high and wide but SCARY!!!!
