In Bangkok, I've noticed that many local and international chains, as well as a number of one-off's, have discount cards and/or frequent diner programs. A few which come to mind are: MK, Black Canyon, Sizzler, Fuji, Daidomon, See Fa, S&P, and dozens more that I could list if I pull out my cards. As a matter of fact, it almost seems like sport in BKK to see who has the thickest wallet full of dining cards.
