Yesterday I pulled into a filling station to fill the tank (these days I find I can get about 500 miles from a tankfull) and noticed all the diesel nozzles were covered. Cashier said "We've had no diesel deliveries".
Now, I'm led to believe that tanker drivers are certified differently to say, someone with a curtain-side trailer: same goes for loose powders. So the question is this: where have all the tanker drivers suddenly gone? After all, you must need a certain skill set to safely deliver several thousand gallons of highly volatile liquid...? Think about going round a roundabout and all that liquid wanting to keep moving in a different direction.
