Am afraid I have to disappoint you ... None of the PRC whore in GL could utter even elementary English let alone basic English. The max they could say is Hello/thank you/yes/no or perhaps - fuck!
You might have more chances of bumping into PRC FLs who speak basic English in sleazy watering holes like Orchard Towers, The Brix (basement of Grand Hyatt) and Ce La Vie in MBS 55th Level. Of course the number of non-PRC national FL who ply their trade there may outnumber PRC FL.
I have came across non Chinese punters patronizing GL ... not sure how they managed though ...
Enjoy!
