Formula & Methodology

💡

Did you know? The standard 15–20% restaurant tip in the United States is a cultural norm rather than a legal requirement. The practice of tipping originated in 16th-century England in coffeehouses, where patrons would leave extra coins "To Insure Promptitude" — the acronym T.I.P. is a popular (though disputed) folk etymology.
