No sharing please !!

Have you ever heard of this English language before ?

No by two …or  One by two,   is a funny phrase typically used in India.No other country in the world uses this phrase to my knowledge.

This phrase is typically heard at tea/coffee/soup/juice shops. What does this phrase convey?

One by two :   Here the item is divided into two roughly equal portions for sharing and invariably the shop owner has to provide an extra cup,without charging.Now the two friends can share the cup of coffee equally between them,just paying only for one cup.

No by Two:   Here the shop owner ( by displaying a notice as shown in the photo ) makes it clear that sharing of one cup of coffee is not allowed ,neither he is willing to give an extra empty cup or glass
