The app is kinda non-intuitive. Its grab app, but u cant pay with someone else's grab pay? You have to go all the process of transfering from someone else's grab wallet then only you can pay with someone else's wallet. Makes paying for someone else is unnecessarily hard. The filter to choose restaurant or shop also bad. Say, i want a choose all restaurant except non-halal, i have to tick all the options (hundreds of them) except non-halal. Why cant you just make a tick all button? Geez
