Gas as in petroleum. In the UK, this was caused initially by a constraint on having enough drivers for the trucks, which lead into a few local shortages. The fear came into that and people rushed to fill their tank. The system being not sized for this, this ended up creating actual shortage with a positive feedback loop. Similar issue in France: strikes were happening leading to local constraints, which was then amplified by people rushing to fill their tanks. In both cases, the situation comes back to normal after a few weeks. This is the toilet paper shortage, or the bank run, all over again.
