Even the priority seat in MTR, the men and ladies give you the seat only when you request them. Sometimes, they are very unwilling to stand up.
I opined that the label of priority seats should declare clearly that "Unless you are the person in need, please leave it vancant". In Hong Kong, the people do not have self-discipine if the rule is not mandatory.
I also hate the people to drag the big case or some trollies without caring other's safety. They just pull strongly. They think that you should give the way to them to pass, otherwise, you get injury yourselves. These situations are always found in Kowloon Tong Station or courier company's staff. Crazy!
