Abel compiled the figures for his card by doing an unscientific but exhaustive survey. He and his employees spent hundreds of hours calling workers, customers and industry execs to determine fair percentages to put on the card, which has more than 60 listings for who gets tipped and how much. You are going to pay the cost of the service one way or the other, either directly through the total price or by leaving a tip. All tipping questions are tough, but think about the salon. It's a virtual mine field of puzzlements.
