Initially I liked to visit Ambal only because they are the only big store in downtown that sells South Indian / Srilankan groceries, although the store is congested and dirty. They put the fish items besides vegetables / spices which is quite repulsive for vegetarians like me. Lately I go there only if I have to as :
1. they sell expired items and don't take it back. They even argue that best before is not the same as expired!
2. they have horrible customer appreciation. As a regular customer, one should be treated with more respect but the main (old) man yells at you if you try to tell him that the product has expired / not good.
They need to be taught how to behave with customers/women.
