Frightened to go in?

No, it's not that TESCO is so scary, we'd all been turfed out because of a fire alarm.
Fire engines came after about 15 minutes but they went around the back to the loading area so just caught a fleeting glimpse of them.
The photo is out the front, we'd all been asked to stay back in the car parking area. After another 15/20 minutes the staff said the fire service advise us to go further back.
In the end it was all for nothing, no fire but something must have triggered it so they had to investigate.
As we went back in, after 45 minutes in the car park, I joked with some staff that it was probably "one of you lot having a fag in the cold store", gave them a laugh after all of the tension and moaning they'd had to put up with.
Many abandoned trollies inside so the staff were mostly occupied with putting the produce back onto the shelves for a while!
