We Japanese pronunciate "Thank you" like "San Kyuu" because we don't have the consonant of "Th" and use "S" as similar voice of "Th" in our ear. 3 in Japanese is pronounced like "San" while 9 is "kyuu". So we use 39 as a symbolic expression of "Thank you" as "San Kyuu" in a casual occasion like in SNS or a messaging.
