A Guide To Holiday Tipping ‘Tis the season to show your gratitude to the people who help you throughout the year.   Here are some guidelines for holiday tipping from the Emily Post Institute: Mail Carriers: a gift or gift card worth $20 or less (cash cannot be accepted). Trash collectors: cash or a gift card worth $10-$30. Teachers and coaches: a small item or gift card – or join with other parents for a larger gift. Babysitters or pet sitters: a gift or cash equivalent to one night’s pay. Nursing home employees: the best option is food or flowers that can be shared among the entire staff.
