Korat had it's name changed to Nakhon Ratchasima, but people, mainly Thais still call it Korat. this is very confusing to visitors as all the road signs say Nakhon Ratchasima and not Korat. Bangkok will probably be the same. Thais will shorten the name, as they do now to Krung Thep or stick with the easily recognised name of Bangkok. These office wallers have too much free time on their hands and are trying to justify their positions.
