Sweet as always

Ok, in Canada at least, they do employ plainclothes LP, especially watching out for the meat, self serve food, and supplements areas. The security company they hire (in BC) is active in high shrink BC liquor stores, best buy and Whole Foods. They're the only company in BC (according to an employee I know) that is allowed to hands on arrest you or follow you off of the property and arrest you later.

Hopefully that helps. Not sure if it transfers to other places outside BC, Canada
