On business
Buena mano, which literally translates to "good hand," is a concept wherein the first sale of the day is believed to bring good sales for the rest of the day. The money received from the day's first transaction is patted on the goods for good luck.
I have always thought this was a Filipino thing. But, wrong, this is also practiced in Myanmar! I was very surprised when after we bought some stuff, the lady started patting her goods with the money! (I just don't know what they call it there.) Have you observed this in other countries, too?
