Lidl

Standing in the corner with an A2 sketchpad and a mountain of pens falling at my feet, I caught the attention of the store manager. 'You can't draw in here for copyright reasons, you need permission from headquarters'. A bit flustered I replied 'Don't worry, my work is quite abstract and I won't make any reference to Lidl'. He came back 4 hours later nearing the end of the drawing and said 'Oh, it looks nothing like Lidl, carry on'.
