Most stores do not encourge physical restraint in a theft situation as a citizens arrest cannot be made - I'm referring to petty theft, not nicking the till.
However, the police will rarely take action against a quick thinking employee that legs up and sits on a thief making off with a telly under his arm.
So essentially if you can manage shoplifting well enough to instill a little bit of doubt into the mind of the security, you're pretty much home free?
You may well be right but I dunno, that really seems a bit lenient to me.
Okay, I'll answer the question of
How about the store revoke the membership of the member because he brought in a guest who refuse to comply with the rules?
I think that is PERFECTLY fair and legitimate and fully within their rights.
The member would just tell the friend to let them check your bags. If the OP doesn't then, i dunno, argument ensures in the store between the member and the OP.
I was talking in general with that question, it just seems to me that if security have virtually no powers to actually stop you, shoplifting would be a piece of cake. A regular high street shop wouldn't have a membership to revoke.
