Since the SARS outbreak in South China in 2002-2003, HK residents have become more aware in terms of personal and public hygiene.
The elevators all have a layer saran wrap over the buttons that gets changed out or cleaned several times a day. Similarly handles and handrails are regularly disinfected.
Before you enter a building or a block of flats, you will walk on a bleached rug so that your soles are freed of germs.
Most stores and public toilets have hand sanitizer dispensers. Regarding the latter they are much cleaner than the average lavatories in France. Besides there is always a cleaning lady on the premises who regularly mops and cleanses. Finally if you are dissatisfied with the cleanliness of the place there is the phone number of a person you can contact.
Do you find that people are as careful in your country?
