I worked in private hospital. Although we don't have that many parents coming from mainland to use our facility, it was worse enough to take care of them. They are the worse group not only they seldom follow your rules and regulations, but also use their right to manipulate you. They smoke in patient's room, they talked loud and disturb the others, they cook food by their bedside, they washed and hang their underwear in the bathroom. All kind of things have given us so much headache. With that kind of attitude, don't you think it has no negative impact to our society?
