Grandpa can shop without getting tired

My grandpa can finally shop without getting tired a lot and we can save the "yam cha" money everytime he got tired.

We call it his super chair. Its a transit wheelchair that can be folded and carried in a carrying bag. My grandpa likes to push it himself because he say its more stable than a tongkat and he can walk faster. The best part is...he can sit on the chair when he's tired!
