• Hotel porter toting your bags: $2 to $3 per bag. Room service with gratuity included on the bill: $2.

• Room service without gratuity included: 20 percent of the charge.

• Toiletry/towel delivery: $2.

• Doorman if he hails your cab: $2 to $5.

• Concierge after guest's request: $5 to $15, depending on how difficult the task is (like procuring sold-out theater tickets).

• Housekeeping: $2 to $5 per day.

Etiquette coach and trainer Constance Hoffman, of Social and Business Graces Inc. in Los Angeles, says, "Don't leave the maid's tip on the nightstand as that has sexual connotations. Instead, put it on the desk or a counter."

Also, the cleaning person may change daily, so give a tip each day before leaving the hotel so the housekeeper who makes up your room will get the money.


Tipping the wait staff

The size of a restaurant gratuity depends on how well you are served, including whether your order is correct or if your server checks on you after you receive your food, says Hoffman. Don't base your tip on the food's taste; the server has no control over it.

Hoffman's tipping guidelines:

• Restaurant wait staff: 13 percent to 20 percent of the bill.

When your party stays through the time that the restaurant could seat and serve others, tip twice the amount. Hoffman says you should always leave a minimal tip, even with abysmal service. Tips are generally shared by the restaurant's workers.

• Takeout: Nothing is necessary. But if you receive some service, like a waiter packaging your food, then tip $1 to $2 or up to 10 percent. For sushi, tip 10 percent for its preparation, Hoffman says.

• Tip jars at fast-food counters: Nothing required; it's your call.

Travel tipping

When you're on a trip, how much you tip can be a quandary. Here, Patricia Rossi, a Tampa, Fla.-based business etiquette expert at PatriciaRossi.com, sorts it out.

Rossi's tipping instructions:

• Cruise employees: Tipping policies vary between cruise lines, "but each one tells you when you board what is appropriate," says Rossi.

• Airport curbside check-in: $1 to $2 per bag, more for oversized bags.

• Taxis: 15 percent of the fare.

• Airport shuttle bus drivers: $2 to $3.

• Limousine drivers: 10 percent to 20 percent of the bill.

• Roadside services for a rental car: No tipping required.

Farley adds, "Roadside service is situational, like if someone changes your tire in subzero temps, you should tip them."


Special events

With all that happens at major events like weddings and funerals, giving gratuities might be easily overlooked. Farley, the manners expert, offered these recommendations.

Wedding tips guide:

• Wait staff: 15 percent to 20 percent of the catering bill.

• Bartender: 10 percent of liquor bill.

• Coat room/bathroom attendants: $1 per guest, paid by the host.

• Disc jockey: $50 to $100.

• Presiding official: Not required but not more than $100.

• Altar boys: $10 to $15.

• Wedding planner: $50 to $100. If it's for the planning firm's owner, don't tip.

Funeral tips guideline:

• Presiding official: $50 to $300 if an honorarium is not preset.

"Any tips for funeral home staff are handled by the funeral home," Farley says. "Sometimes those fees are itemized on the bill (as a gratuity), or they can be included in the overall price that the family pays."


Reward salon and spa workers

Many workers in the beauty business get paid a commission only or minimum wage plus a small percentage of the fee. Remember them with these gratuities suggested by etiquette coach Hoffman.

Salon/spa tipping suggestions:

• Massage therapist: 10 percent to 15 percent of the charge.

• Hairstylist: 10 percent to 20 percent.

• Manicure or facial: 15 percent.

• Barber: $2 to $3.

Don't forget your four-legged friends:

• Pet groomer: 15 percent to 20 percent.

Your best gauge is to consider the service you're getting and to give what's appropriate, says Hoffman. "Any tip given with a genuine smile and a 'thank you' is better than nothing at all," she says.
