Understand 'shroff' as part of Asian culture where these money-changers are a common sight. Local markets often have a shroff nearby for traders and tourists.
Pro Tip 2/3
Not a Banker
'Shroff' should not be confused with a banker, though both deal with money. I prefer a shroff for quick currency exchange rather than waiting at a bank.
Pro Tip 3/3
Travel Specific
The term is useful for travelers in Asia needing to exchange currency. Remember, find a shroff to get local currency once we land in Bangkok.
