Yes it was a problem... Like my conversations with the store girls, I carried it well until at the end when everything starts to unravel.
at first I thought about dragging it into the changing rooms and shove it down my pants, but being so big, they may have noticed.
I then contemplated wrapping up one of the shop girls in it and leave with her. If caught I would be let off on the lesser charge of shop lifting the poster and only prosecuted for kidnapping (phewph they wouldn't suspect the smurf poster was the real prize).
I was contemplating driving my car in to the shop as a smash and grab but they are in the middle of a mall and its a long drive through many pedestrians. Again they may have noticed.
Then there was the tunneling project but that sounded like too much work.
Cat burglar, at night coming in through the ceiling with lots of smoke, a silly black outfit and a harpoon gun. This was tempting I must admit.
In the end the shop girls were just happy that I leave them alone and take the poster and just "don't come back here again, you crazy man" or words to that effect.
Serves me right for thinking out aloud I guess.
Sometimes I feel it should be simpler just to ask for a rubber band! But then when have I ever done things the simple way?
