Not being mean or anything!
But honestly I've travel in alot of places including in Hong Kong, Malaysia and the US.
But none come close to the attitudes of Singaporean Sales men and women.
Not only do they completely ignore especially if your not Caucasian, but some of them won't even sell you stuff in places like Sim Lims or Funan.

The worst part is when my mom asked a sales lady in Tangs, she literally wanted to punch my mom face for asking questions, well she did it behind our back, caught some glimpse of what she was trying to do.
What is it w/ Singaporeans? I feel like they are living in this invisible pedestal and most tourist aren't even aware with. And that using they're saliva is quite expensive apparently. They hate being asked! MOST OF THE TIME!
