It's Only Human Nature?

A few UK Shell and BP petrol (gas) stations have been forced to close, having run out of fuel. There is said to be plenty of petrol and diesel at the refineries. There is, however, a shortage of tanker drivers to deliver it to the pumps. People have been instructed not to 'panic buy', as this will simply make the situation worse. Result? Large numbers of motorists queuing outside petrol stations to fill up. Any mention of closures, was always guaranteed to get the Brits reaching for their car keys.
