Uncle. Teh-o jit puay.

I always ponder over lunch.
Ponder how come my diluted teh-o is worth a whopping $1.

lets do some maths to calculate the price of teh-o vs a good puerh.

Teh-0
500ml cup = $1
so 1 ml = $0.002

Puerh.
5 grams of tea can make 7 infusions of 150ml of tea
(assuming teapot is 200ml and 50ml was the space taken for the leaves)

so 5 grams can make 1050ml of tea
a typical cake is 357 grams. So it can make 74970ml of tea
therefore 357 grams of tea in coffeeshop = S$149.94
Therefore the price i pay at coffeeshop is equivalent to buying a puerh of value up to S$149.94

For S$149.94 i can easily buy a nice aged puerh, probably yr 2000?
Why do I have to put up with the expensive teh-o when I can buy a delicious aged puerh?

OOi. Uncle. Serve me something better please.
