When you're on a trip, how much you tip can be a quandary. Patricia Rossi, a Tampa, Florida-based business etiquette expert at PatriciaRossi.com, sorts it out.
Rossi's tipping instructions:
- Cruise employees: Tipping policies vary among cruise lines, "but each one tells you when you board what is appropriate," says Rossi, who wrote "Everyday Etiquette."
- 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."
