In the government's fire safety ads those days, people were advised to use a pointed high-heel to break the glass and press the alarm switch. Maybe because of increasing complaints in recent years, they have taught people to use keys to break the glass instead.
以前政府啲防火廣告，成日教人用斗零踭打碎塊玻璃去撳警鐘掣，可能近年俾人投訴得多先至改咗教人用鎖匙去壓碎塊玻璃。
