Holiday tipping

Not sure how much to tip people whose services you enjoy? The rule of thumb is to tip the value of a service. 

• Personal trainers get a session's worth in cash or gift. 
• House cleaners get the cost of one service, though most people tip $35. 
• Lawn people get $20-$50 each. 
• Building staff get $25 to $50, with most people tipping $25.
• Hairdressers get the value of a service, with most folks tipping $20.
• Teachers get gifts with a value of around $20-$30 
• Newspaper carriers typically get around $10-$30, with most folks tipping at $15
• Mail carriers may not accept gift above $20 in value or get cash or cash equivalents, such as gift cards
• Dog walkers get a week's pay. 
• Babysitters of hellions should definitely get tips. A night's service. 
• Delivery guys typically get $5, though if they have to hoist a refrigerator through two flights of narrow staircases, you might want to be more generous. It really, after all, literally backbreaking work.
