Tesco

I walked in through the front door and all the lights went out.

It was like being at a fireworks dispaly as all the shoppers went "oooh" in unison.

I felt quite guilty for some strange reason and had an urge to shout out "sorry".

All I did was walk in at the wrong time.

Five minutes later they came back on again.

"Aaaaah" went all the shoppers.
