Diluted coke. Half fries.

I bought 4 Large Big Mac meals from McDonalds Tyger Manor this morning for myself and my colleagues . The coke tasted diluted, doesn't taste like coke AT ALL. And the chips was half. For as long as I had McDonalds I've never received half chips from ANY MacDonalds until this morning. This is so disappointing because I prefer your fries above any other restaurant. This is not on !!!!!! And this on our empty stomachs.
