Engineers at a very large paper mill where I worked many yeas ago were issued with oval canvas tool bags with a wooden base. The mill was spread over a large area &, rather than waste time taking your tools back to the shop at meal breaks, it was standard practice to stash them in a convenient hidey hole. You had to make sure that nobody saw you, not so much because you’d get your tools nicked but it was standard practice to fill any tool bag you managed to find with hot, wet paper pulp & stick it on the largest nearby heat source or steam pipe you could find. In less than an hour the pulp would set solid & on return you’d find all your tools encase in a solid lump of paper mache; it took ages to break out your tools again.
Another one was to empty the fire (water) bucket from an elevated walkway know as No5 bridge onto the skivers standing in the designated smoking area below.
Yet another was to spray the fire hose over the partitioning wall that divided of the w/c traps from the changing rooms.
You’d probably get instant dismissal for doing any of those now.
