I wish I can give zero star if I could but I can't...

I wish I can give zero star if I could but I can't....however, today I went to T&T @ MetroTown approx between 2:00 pm - 2:30pm I purchased a pre-cutted watermelon from their cold-cut sandwich section; when I returned to office to enjoy my watermelon, one of the piece actually have a unknown object stuck within the melon, at first I tasted in my mouth , then I split out only found it it was actually a piece of yellow HUMAN NAIL!!!!!! ><...this is by far the most disgusting experience, I ever had.....later I had to washed my mouth several time and made myself vomiting, I would never buy pre-cut ANYTHING from Metro Town T&T anymore...or any of their cook food...if they have HUMAN NAIL in their pre-cutted watermelon , image what else would be there in their other cooked production.
