No a law wasn't broken but what would've happened if I walked away? Would they have tried to detain me? If not, does that make the search optional? If so, would it be a lawful detention?
Probably, because by refusing a simple check you'd likely then give them reasonable grounds to suspect you were attempting a theft and they could thus detain you because of it i'd have thought.

People whine in GD all the time, I think it's being given too much attention in this thread to detract from the fact that we haven't really got into discussing the actual law (no more T&C quotes please!)
Once would've done but when you have a weak argument you have to rely on repeating yourself for emphasis.
