Shortest time you've stayed at a new job?

[Burney]

Decades of layers of super-heated Marmite steam solidified into a solid gloop (yes, a solid gloop, get your head around that, if you can) of such stickiness and malodorousness as to make the strongest of men blanch. We tied scrapers, then chisels, then pressure washers, then steam cleaners, and nothing made any impact on it except to anger it and cause it to release wave after wave of noxious Marmite gasses.

Each day was like a Sisyphean lifetime.

Could you not have licked the walls?
