Spies among us

I did some retail therapy at the new Sam's Club in Etobicoke this morning. I went to check it out, and truth be told, to look for a good book to lose myself in today (mission unsuccessful). While I was there, I came across an employee of the local Costco. I razzed her: "You're not supposed to be here!" Turns out she was there as a spy from Costco. She whispered to me nervously while glancing around to see if her identity would be discovered by a Sam's Club employee. If caught, she would be kicked out. Wow. I knew this stuff happened (I'm sure Sam's Club is over at Costco all the time), but I had no idea that they took it so seriously. Probably as close as I'll ever get to cloak and dagger, apart from the occasional James Bond movie.
