"SIRIVAT SANDWICH" was founded in April 1997 when Mr.Sirivat and his wife, Mrs.Vilailuck, started making and selling the first 20 sandwiches on April 20,1997. It took them 6 1/2 hours to sell them. Mr. SIRIVAT VORAVETVUTHIKUN, 59 years old, was a famous local stockbroker and investor. He had made his fortunes in the local stock market until the stock market crashed as well as his luxurious condominium project in early 1997. His 20 employees showed their intention to stay with Mr.Sirivat who had lost financial creditability and fortunes. He and his wife decided to cut down all expenses, except employees' salaries, in order to survive e.g. they gave in a ฿100,000 office rental per month to rent an old townhouse for ฿15,000 a month. His wife suggested making and selling sandwiches.

      Today, Mr.Sirivat is still selling sandwiches to keep his employees (although some had left) survived as well as some unemployed people whom he thoroughly understands their plights. For him, he is still struggling with hopes since Thai people are supporting him. More than 140 local medias have been continuously making his 'fighting spirits' known to the public since the 1997 economic crisis. In addition, CNN, CNBC, BBC WORLD, NHK, and more than other 99 international medias have made his logo (Baht floating with a balloon) known all over the world and called him 'The Sandwich Man' and 'Mr.Sandwich of Thailand’. BBC WORLD has also added ‘Sirivat Sandwich’ in their ASIAN INNOVATORS in 2003
