There are no hard-and-fast rules for tipping in Israel. Locals do not tip taxi drivers. In other situations, a gratuity for good service is in order. If you’ve negotiated a price, assume the tip has been built in. If a restaurant bill doesn’t include service, locals tend to tip 12% to 15%—round up if the service was particularly good, down if it was dismal. Hotel bellboys should be tipped a lump sum of NIS 10 to NIS 20, not per bag. Tipping is customary for tour guides, tour-bus drivers, and chauffeurs. Bus groups normally tip their guide NIS 30 to NIS 40 per person per day, and half that for the driver. Private guides normally get tipped NIS 100 to NIS 120 a day from the whole party. Both the person who washes your hair and the stylist expect a small tip—except if one of them owns the salon. Leave NIS 10 per day for your hotel's housekeeping staff, and the same for spa personnel.
