Avoid fixed pickup assumptions
Mall traffic, stopping rules and crowding can change. Use WhatsApp to confirm a practical point based on safe stopping conditions and passenger readiness.
Share the right context
Tell the driver whether you are at the mall, hotel, JB Sentral side, restaurant, supermarket or a specific entrance. This is more useful than only sending a mall name.
Plan return before bags pile up
If you expect many shopping bags, stroller or elderly passengers, decide one contact person and a target pickup window before the mall gets busy.
