There I was in Morrisons this evening, with nothing but a loaf of bread, 2 pints of milk and a jar of horlicks.
I was stood in the shortest of several ENORMOUS queues patiently waiting my turn. (It was a hand baskets only till).
Then, a very nice Morrisons lady came up to me and said 'if you would like to follow me, I am opening another till down here'.
How very lovely of her I thought. I reciprocated the good deed by letting the 2 people who were before me, remain in front of me.
ONLY just as we make our way to the till, along comes said smug pusher in-er, manages to barge her way past me and the other 2 customers at the speed of light and position herself at the front with her overflowing TROLLEY!!!
She smirked at us all as we exchanged aghast looks and proudly announced 'beat ya, ya losers'!! 
She then took great pride in fannying about with her packing 
I felt like lamping her one with my loaf of bread!!
