Science based lesson for my stepson´s after school job. When serving in a restaurant:

• make sure you are seen as an individual
  • wear something that makes you distinguishable from other waiters/waitresses
  • introduce yourself to your guests by name
  • entertain the customer with simple jokes or puzzles
• recognize customer as individual
  • call customers by name
  • squat next to the table so you are on eye level and more intimate with the customer
  • repeat customers order, slightly mimicry customers tone and behaviour
  • briefly touch the customer, preferable at the shoulder
• tips increase with bill size, so it´s sell, sell, sell
  • suggest appetizer
  • check during dinner for new rounds of drinks
  • suggest dessert
• make paying the check enjoyable
  • forcast good weather
  • write Thank You on check
  • draw little pictures on check
  • use tip trays with credit card emblem
• give customers candy or chocolates
