I've been using Grab sporadically since it was called MyTeksi and more recently Uber. I've never been able to get a promo code that was not fully redeemed. But I don't complain pun. That's because I really need to go where I need to go. My destinations are usually high fare, so a discount of RM3 or RM5 doesn't mean much to me.
It seems that in their war with each other for market share, Grab and Uber has been giving out so many discounts that it has created a kaki tempang culture in people. Too lazy to walk or use bicycle, use promo code get free rides. It has also created a lot of baby birds who always want to be fed discount codes.
I never understood anyway why Grab and Uber give free rides to kaki tempang people. These people will never use the service anyway if there's no promo code. As can be seen in this thread, when there's no discount, banyak complain. These are for profit businesses. They cannot give discounts all the time forever.
But now as a driver, I don't mind if Grab wants to give discounts to help me hit my incentives target. But I've also noticed in the past week, very few of my riders used promo codes, but I'm still able to get a lot of incentives. So there's still organic demand in the market.
And when people say RMXX for Grab and Uber is expensive, what are you comparing it to?
The promo code basically has no meaning if one would have the mindset of “free ride” as the rate have been inflated anyway. It just a marketing gimmick to attract people.
