I'm sure I have a weak regulator to thank for shafting the consumer and limiting my choice in the area so I have to endure three trips to Tesco in the week, one to the supermarket, one to the Tesco convenience shop and one to the Tesco petrol station.

All three had their own dissatisfied tale to tell about Tesco Customer Service.....

1. At the supermarket the groceries were being scanned as if it were the new speed event in the 2012 Olympics. As I struggled, near defeat, with separating plastic bags and trying to pack, the cashier was finished and was now busy texting on her mobile phone, completely oblivious to me.

2. At the partly flooded convenience shop I bought a chicken ceaser wrap. The cashier seemed to clear a bonus of £2 from the transaction. I handed him £4, and watched as he registered £2 cash received on the till. What happened to the other £2?

3. At the petrol station - I wrote about this earlier - a queue even though there are free pumps. What are the staff doing? From the corner of my eye I observe a manager emerge from the nearby supermarket. He takes a closer look, albeit at long distance, at the queue and scuttles back inside the supermarket. What do the staff do? Nothing!

I think the petrol stations are designed to work without supervision. When I finally make it inside to pay the two chuckling cashiers decide to swap tills while us customers wait.

Going to Tesco gets you in such a bad mood! Grrrrrrr......
