In Italy, service is always included in the menu prices. It's customary to leave an additional 5%–10% tip, or a couple of euros, for the waiter, depending on the quality of service. Tip checkroom attendants €1 per person, restroom attendants €0.50. In both cases tip more in expensive hotels and restaurants. Tip €0.05–€0.10 for whatever you drink standing up at a coffee bar, €0.20-€0.50 or more for table service in a café. At a hotel bar, tip €1 and up for a round or two of cocktails, more in the grander hotels.
For tipping taxi drivers, it is acceptable if you round up to the nearest euro, minimum €0.50. Give a barber €1–€1.50 and a hairdresser's assistant €1.50–€4 for a shampoo or cut, depending on the type of establishment and the final bill; 5%–10% is a fair guideline.
On private sightseeing tours, tipping your guides 10% is customary. In museums and other places of interest where admission is free, a contribution is expected; give anything from €0.50 to €1 for one or two people, more if the guardian has been especially helpful. Service station attendants are tipped only for special services. On off-hours there may be station attendants not in uniform working just for tips. Give €0.50 to €1 if they fill up your tank.
In hotels, give the portiere (concierge) about 15% of his bill for services, or €2.50–€5 if he has been generally helpful. For two people in a double room, leave the chambermaid about €1 per day, or about €4–€6 a week, in a moderately priced hotel; tip a minimum of €1 for valet or room service. Increase these amounts by one half in an expensive hotel, and double them in a very expensive hotel. In very expensive hotels, tip doormen €0.50 for calling a cab and €1 for carrying bags to the check-in desk, bellhops €1.50–€2.50 for carrying your bags to the room, and €2–€2.50 for room service.
