About grabshare:

1. Passenger 1 wan to go from location A to C, then another notification from passenger 2 waiting at position B who also wan to go to position C, it took me quite a while going to passenger 2, the passenger 1 are not happy about this because it takes more time to arrive to his destination.
2. Passenger 1 wan to go from destination A to B, but then passenger 2 wan to go from destination C to D, 2 different passenger from different pickup location to different destination.
3. Pickup 2 passenger, received a notification from passenger 3, going to fetch passenger 3, then passenger 3 saw there is another 2 passenger in my car, immediately cancel the request.

So to all grab passenger, yes grabshare is cheaper, but there is a consequences, if you guys are ok to wait for us go fetch another passenger, then fine, if you guys ok to share your ride with another stranger, then fine...
Don't ask why there is another passenger and why we going to other places...
This is real life, unlike the ads playing in radio, the passenger saying "hi" to each other, i never heard my passenger greets another, i only see grumpy and fear in their face...
Choose well, how much you paid is how much you get...

I can wait, but not the passenger, 9 out of 10 grabshare passenger are pushy, they always said "drop me 1st, i'm in a hurry" while it is their cheapskate attitude to choose grabshare without knowing there will be another random passenger coming on board...
Imagine there is 3 person in 1 grabshare, then another 3 person also using grabshare, that is total of 6 person in my car, i'm not driving a van/mpv, for sure it won't fit in my car...
Conclusion: if you in a hurry /not a good in patience /not a sharing type, please use grabcar not grabshare, i have enough with their complaints and stupid question when ever i'm going to fetch another grabshare passenger

1 word for them: cheapskate

Grab should rethink again about grabshare, seriously...
The algorithm of grabshare is chaotic

Fetched passenger A, "i'm in hurry, please drive faster and drop me 1st"
Fetched passenger B, "i'm in hurry, please drive faster and drop me 1st"
How to satisfy 2 king in my car?

I did received and fetch some reasonable passenger, but some only, the rest is really really difficult to handle...
By the way now the grabshare job are getting less, i think most of the passenger already knew the pro and con of the grabshare...

Seriously grab should look at the algorithm of grabshare
