For all these farking reasons, I'll NEVER take ang moh.
Even in Taxi Stand, if it is Angmoh, I will rather put busy and
drive off..much to the chagrin of the ang moh pax and the
atonishment of others in the Q.
Roadside is best, on signal, smile, put busy, off signal, drive
off. 
Even PRC who insist on calling their destination in Mandarin, I
will avoid...at least, they try still ok..even ABNN grandfather who
don't speak English will make an effort...can you imagine the road
name in their own language??
