Vietnamese Milk Tea

What a cool nice drink for a blazing saturday afternoon. It's actually milk tea but was really good. The interesting thing is when Derrick ordered this at the Pho Thai (Vietnamese restaurant), he asks:

Derrick: "Does the Milk Tea have milk?"
Waitress: "No, this other has milk"
Derrick: "k, i have that instead"

Now, milk tea does not neccessary have milk... Lesson for every1
