Utterly no respect for the elderly and 有眼不识泰山.
That uncle is not a small fly in Kong Chow Wui Koon, hence he is given a chance to stand in front the queue. That Lion Dance troup belongs to the association, so uncle has to wear the red shirt. Greet and shake hand with elderly is considered "Good Luck", since he was representing the 国术沙龙醒狮团. This Gan 做咩都无运行。Uncle is nice guy, he won't get offended by this small issue.
Kong Chow Wui Koon lion dance and its 国术 is quite popular and solid, and truly represent the Canton culture in Singapore.
