Tip percentage declines as bills increase

Psychologists at Washington University in St. Louis have shown that the larger the bill, the smaller the tip percentage that food servers, hair stylists and cab drivers receive. Compiling data from nearly 1,000 tips left in restaurants, hair salons and with cab drivers, the researchers found that the percent of the tip actually decreases with the amount of the bill across all three tipping situations. Their findings also indicate that with bills more than $100, the percent of the tip levels off — if the bill is $200, the server is likely to receive the same amount as if it were $100.
