In the old days, Thai people ate with their bare hands. And there was no specific time to have meals. When P. Pibulsonggram became the third Prime Minister of Thailand (1938-1944), he launched a campaign to make Thais consume not more than four meals a day. At this time also Thai people started to use a spoon and fork as a tool for eating food. The reasons behind this campaign were to show civilization and to prevent germs existing on the hand from getting into the body.
