Advance signs for motorway service areas display the location, operator, main and subsidiary providers and facility icons, but not the fuel brand, which is very important for many drivers with fuel payment or loyalty cards. One of the icons often shown is a 'green' pump, which nowadays is totally superfluous. How simple it would be to leave this green-coloured to indicate BP sites, but change it to yellow for Shell and red for Esso? Problem so easily overcome.
