I did a gig last night and I asked some comedians what they missed most about Woolworths and why THEY thought it had vanished from our high street. They all said the same two words to me - pick n mix and shoplifting.
In the context of modern standup, a good comic's material comes out of their life experience and represents their analysis of the world. Stealing it means stealing their thoughts, their voice. What theft is more serious than that?
