In with anger out with love

I'm down with Dr Weil at the moment and have started his 8 weeks to optimum health so it was off to Tesco this lunchtime to stock up on a few nutritional and spiritual essentials.
I only had a few bits and waited at the till whilst a couple of elderly ladies checked out their shopping. I waited and waited and waited as they struggled to put their produce in the bags but chilled out with a few suggestions from Dr Weil's cannon of philosophical hints. After a good three minutes the cashier asked the old girl to pay, she pushed her card in the slot and then failed the chip and pin request FOUR times. It was a blood bath, the cashier's help light flashed so I swept my shopping back in the basket and tried to find another till.
There was more trouble here. A woman questioned her bill and began to add it up herself with a CALCULATOR! I felt a bit dizzy so I began my breathing exercises. She went then the next woman started yarping about growing her own vegetables in Devon and how she fancied maybe over wintering somewhere hot as there's not much sunshine here.
She was in no hurry to pack her shopping or pay, a huge wave of rage came over me and the flowers which Dr Weil suggested I buy for my desk to bring cheer were nearly destined for her behind "I'll give you where the sun doesn't shine" I thought.
The two women who caused the trouble to begin with walked passed me like dominoes leaving the catastrophic chain of events in their wake.
I need to swallow the little book of calm.
