I was doing work experience for an office when I used the toilet. The cubicles were made of thin boards with gaps under the doors and above the walls.
need I say more? I had eaten lots of fartable things like cabbage and onions, and to 'suffocate the sound' I smothered my hole with a wad of tissue.
For some reason this never worked. the noise slipped out around the edges in a massive heat steam, and echoed in the toilet bowl like a trumpet.
And yes, staff members were close by. And it was easy to guess it was me coz it was a small office with only 3 girls working there...process of elimination!!!
