Tipping ("propina") is not generally considered mandatory in Spain, and depends on the quality of the service received. In restaurants the amount of the tip, if any, depends mainly on the kind of locale: higher percentages are expected in upscale restaurants. In bars and small restaurants, Spaniards sometimes leave as a tip the small change left on their plate after paying a bill. Outside the restaurant business, some service providers, such as taxi drivers, hairdressers and hotel personnel, may expect a tip in an upscale setting. In 2007 the Minister of Economy, Pedro Solbes, blamed excessive tipping for the increase in the inflation rate.
