Anti-static gloves at a petrol station

 

Plastic gloves have become ubiquitous at petrol stations in the last 18 months. I assumed it was to do with Covid but it turns out they are supposed to stop static electricity producing sparks that ignite petrol vapour. I am still wondering how it works. My first theory was that they conduct electricity better than normal plastic to allow built up charge to flow away. I measured the resistance of a bag - see below - and the resistance was off the scale even with the clips close together. So that can't be the answer.
