I was in Tesco once and there was this fire alarm going off. But everybody was ignoring it and just carrying on with their business, so it made me assume that maybe the alarm sound wasn't a fire alarm and that perhaps someone had accidentally set something off and couldn't get it to switch off. Then one of the staff announced over the intercom that there is a fire drill and that everyone must immediately evacuate the building. So hundreds of people all had to exit out of the store, which made me feel very stressed, and we all had to stand there in the car park only for a couple of minutes. Then they let everyone back in again. I didn't see much point in all that.
So the point is, if supermarkets did have fire drills regularly, it would be hell trying to get all the shoppers out then back in again every week, and shopping is generally not something people like to be interrupted in.
