Bakshish, also spelled as baksheesh or baksis, is a term used to describe a gratuity or tip given to someone in return for a favor or service. Though commonly used in the Middle East and South Asia, it has become a part of the English language as well. Synonyms for bakshis include tip, gratuity, bonus, reward, payment, commission, honorarium, and allowance. While these words have their own subtle differences, they all refer to a financial incentive given to someone for providing a service or doing a favor. No matter what the word, the intention behind it is the same - showing appreciation and thankfulness.
