I was conversing with a Malay Vet from the RA,it was mentioned about Char Whallahs,During the time of the Manchester Regiments time in Malaya,the contractor who was responsible for the Char Whallahs,and Dhobi, was I believe called Khadar Bux,char whallahs where located at each company location and provided an excellent service in the provision of tea and most famously of all egg banjo's,far superior to NAAFI.
