Fire Alarm

Everybody had to evacuate The Farmers Store today.
The fire alarm suddenly went off,(my suspicions were on the builders that are working on the new carpark above!) no smoke was detected but everybody left the building quickly.
The fire brigade screamed up the main street with lights flashing but after a thorough check no fire was found and evrybody went back in to finish their shopping including myself, buying up warm sheets as the nights are getting chilly.
