Spotted...

and how many people walked past and saw what was happening and pretended to be suddenly interested in the contents of thier Pret sandwich?

people aint no good.
Everyone... I wasnt prepared to confront them but they were fast as well. When i saw them i sent the message out. Guess no one wouldve been fast enough unless they happen to walk out at that point.

cant believe though that they just had an electric angle grinder!

But no one asked questions as far a i could see. And im not sure how long they had been at it when i saw it.
