here is a real life example:
dropping passenger in Sunday Pyramid. Upon approaching, received a new request pick up at Sunway Pyramid. Accepted. and within 2 minutes I already arrived. call the passenger, she was caught be surprised. luckily she was already at the entrance if not I would not have waited for her. it is impossible to wait as well. sure kena horn and shoo by the security guard.

so please book only when you are ready to enter the car.

your last statement make sense.

you guys realise that this driver is a platinum rank driver?
look at the pics again. 49 5 stars rating out of his 50 rated trips. is a feast hard to achieve.

nope. do not pin point on road. always use a landmark. a shop like 7-eleven, mamak restaurant, etc. if you put on road will be Jalan Klang Lama for example. the whole stretch of road is Jalan Klang Lama.

for shopping mall example KLCC, just put Coach@KLCC or Mid Valley put Coffee Bean so that driver will know which entrance to go.

most drivers will doubt if receive a request along a long stretch of road. because normally always bangla the main culprit who simply drop their point. I once received a request up on Akleh highway the point. of course I will not accept such crazy request.

so to minimise the doubt. use landmark. it is the safest.
