How rude!!

I was feeling a bit low today so decided to go for a walk which cheered me up. On the way home I stopped at a local Sainsbury for provisions, I was looking at the yoghourts when a member of staff stood right in front of me and started filling the shelves, I asked him, politely, to move but was told he had to do his job - VERY RUDE MAN!!!! Will I go back to that shop again - NO!
