I totally agree with you wiping dry your body or changing the clothing at the changing room when you enter the lift.i have been managing condominium before.others residents will blame the management office for not doing enough.
I experienced everything you said and I feel a shame of myself in foreign countries even thought I'm not a Chinese. Well I'm Malaysian Chinese but for other races, they are unable to distinguish me from mainland's Chinese.
There is a saying in Malay proverb "Bahasa menunjukkan bangsa"; that literally means how a particular tribe or people behaviour is a direct manifestation or reflection towards the ethic.
Doesn’t matter which country you go to; common courtesy and respect should prevail. No matter how poor/rich you are, you should be rich in core values.
