You’d probably be putting your life in danger if you took any action to thwart these “people”.
Yup, I would not want to lock them in my shop. I deal in high end stuff but thankfully it’s not near as easy to carry out or resell as a pair of jeans.
And I got my last NEW pair of jeans for 10 bucks? what exactly is a “high” end pair of jeans? A bigger price tag and a “designer” name?
After watching that video I’d say your life was in danger the minute that mob of “youths” entered the store. That is a scary scenario.
