Fire Resistant…
Now there are two options here*: either the people labelling the shutter simply mis-spelled the word ’shutter’ either accidentally or because they didn’t have enough Us for the label, or someone thought it would be funny to make a swear word on the sign.
My theory is on option 2. And I also believe that they are right.
A fire-resistant shitter? Perfect for when you’ve had a particularly hot curry…
*actually, there’s a third option: that I doctored the photograph… but then you’d have to ask why I would take a photograph of the shutter in the first place…

Because it resides at the place you used to work for perhaps :-0 ?
