I buy weekly green vegetables. Used to be good & fresh. No, no more of late , last 4 to 6 weeks i opened my leafy vegetables to find they are no good & not fresh inside. Tried again 4 days ago & i find both the leafy vegetables have leaves turning dark blackish green inside! Very disappointed,i will not buy green vegetables there any more. The side shop in front of Hock Choon sells fresh & better veges & fruits though 2 or 3 bids more costly.
