Three conditions of cheapness

A written on a board in a tea stall

1. Mast tea 30 Taka
2. Special Tea- 15 Taka
3. Tea-5 Taka
   The protagonist called the stall boy and asked - What is the matter of this 5, 15, 30?
   Boy says - all are the same, which you like to eat
   The gentleman said - okay, give me a cup of tea worth 5 taka
   It was good to drink tea. The gentleman called the boy and asked him to give tea at Tk 5 and Tk 1 in the tips.
   Your five tea tea is very good. If you do not know the tea worth thirty taka, how much better will you, what do you make that tea?

Boy says - We use authentic milk, expensive tea leaves and thick grains of tea at a price of thirty taka. I use tea leaves, water mixed milk and less expensive sugar for tea at Tk 30 per kg.

The gentleman asked - Then make tea with the price of five

Boy says - What do you know, only the standard people drink tea worth 30 or fifteen rupees, and they do not eat whole tea in fashion, leaving them under the cup.
We keep that extraordinary tea on a flax and it is heated to sell at five takas.
