As much as I enjoy my trips to the USA I always come back feeling a little mentally frazzled, although having used my Sat Nav (set to metric) in recent years I've had some relief from road signs I still have to convert weather forecasts from °F to C... but what I didn't expect, especially after complaining about it 2 years ago, was having to do the same on a Virgin Atlantic flight!

Those who argue for the Imperial system of measurement often state that one of it's many great features is it's flexibility and the fact it fits in with everyday things... but I spotted something this week which once again proves that this supposed flexibility is often used as nothing more than a smokescreen with which to confuse the unsuspecting consumer!
