Relive the Pirate experience by telling supermarket security (read: Bounty Hunters!) you are a compulsive shoplifter, then run and hide amongst the racks!
I tried that... There's a bug in this bit though... They're rather dim and walked past me... I think standing next to the Action Man figures in the Toy section disguised me suitably...
Note : not all posts on t'internet are necessarily factually correct...
