This forum has given me many tips, do and donts and many more..
Let me share tips on how I gain from 4.86 to DR 5.
1. Look who is your cust. If possible start a small chat... easy one is to talk abt the location he she want to go.
For example, he want to oval damansara, so ask what is it there, any good place to eat there etc. If Customer layan, then you can continue your conversation. If bo layan, then stop and focus on driving.
2. Try to praise them, i.e if a student taking a certain degree course, puji la sikit, good choice of degree, easy to find job with this degree la etc etc…
3. If late, say sorry due to traffic.
4. When you abt to reach destination, inform them, “we are about to reach. And don’t forget to me a good star ya. TQ”
5. Prepare a tit bits like sweets and offer to whoever you want.
Happy hunting guys!
