Yeah zippy- he's not a full shilling, and usually quite harmless, but he got really agitated whilst in the queue and started ripping twntys up and scattering them, i was gobsmacked.
When he got to the front and came to my till (lucky me!), he dithered for about 10 minutes over cigs and wanted a box of matched with an M on them(!) and then, when paying for them, brought out a fistfull of coins from his pocket which had yellow powder on them all. When I stupidly asked why it was all yellow i was told "oh, that was a mistake, they're supposed to be orange"...!! Well alrighty then!
