Shop i used to work in. Long ramble - sorry:
Old town, old buildings, 2 properties knocked through into one - so unusually large shop floor downstairs and BIG stockroom with open eves roof upstairs. The whole stockroom was full of big free standing wooden shelving units for the stock which were about 10 foot high. You could see through them, but they ran from wall to wall, like a library, which made it a bit like a maze up there. Our little staff room up there was in the opposite corner to where the staircase came up.
Downstairs was fine, upstairs was frankly a nightmare.
If anyone knows that feeling that when you walk into a place you're disturbing something very old and very very pissed off? The air feels quiet and thick. You're entering the home of something which doesn't want you there and wishes you harm. Something which hears you/senses you and rushes to where you are. It watches, more and more malevolent until you leave. You can feel it close to you.
Well it was like that up there. And we were all up and down multiple times per day. There were 5 or 6 of us working at the shop and to cut a long story short each of us hated being in the stockroom alone. Someone was brave enough to admit it once and the rest of us were relieved we weren't the only one! We didn't talk about it much, but got by as best we could by trying to stick to not sending anyone up there on their own. But when it was busy it couldn't always be avoided. The one member of staff who for months was adamant it was all bollocks came down to the shop floor in tears one day saying she had just heard heavy footsteps right behind her as she walked from the staff room up there and cold breath on her neck. She handed her notice in the next day!
The thing which drove me to leave in the end was this:
One morning i had to open up because the manager (6 foot bloke who also hated the stockroom) was ill. Got into shop, did the alarm, locked the door again and started to sort the till. There was no way i was going to unlock the the fire door (stair case door) until someone else arrived! Next member of staff to arrive was 'A' at about half 8. We fiddled with the till together putting off the moment we would have to unlock the stockroom ect.
Then the banging started.
This really really loud banging above our heads - ie on the floor of the stock room. It was slow and steady like someone stamping as hard as they could across the wooden floor up there. The pair of us were moving our heads looking to the point of each bang together, like a pair of cats! We looked at each other. We carried on looking up.
This is the thing though: these bangs were easy to follow, and they traveled diagonally across the ceiling. Like some one stamping their way from one corner towards the opposite corner. But the shelving units up there meant that it was physically impossible to do that so ... ??
After it stopped we waited till all the rest of the staff were in before unlocking the stockroom and the opening the shop. 'A' and i made sure none of us went up there alone that day and i handed my notice in the next morning!
