Singapore is still a tidy place but not as pristine as its image would have you believe. I don’t know of it’s just a poor memory but I’m sure it was tidier 9 years ago when we arrived. I think most of the tidiness is due to the number of cleaners rather than every bodies behavior. For example our street is swept everyday except Sundays by the same person. In my 5 min walk to the station each day, I pass another 2 guys sweeping. So yes it is still clean and tidy, but boy does it take some effort!
