There is a Morrison's on my way home from work, so I swing by to pick up essential cheapo petrol etc.
Last week, the woman behind me in the queue had:
-multipack of WKD Blue
-multipack of Red Stripe
-Tena Lady pads
-cough syrup
And she was debating with her DP whether or not the syrup also contained alcohol.
Last night, I went in to pick up some juice, and the man standing by the display picked one up, opened it, drank from it, said 'Ahh that's better', winked at me, and continued shopping 
Plus every second person is missing at least three teeth. But it is cheap....
