Going to BlogHer '11? Here's a Tipping Guide
I always feel clueless about tipping. This list from editor Chris Morran at The Consumerist even tells you how much to tip your salmon fishing guide, in case you're planning to do that in San Diego in between BlogHer '11 sessions.
Museum Guides — $1 per tour participant.
Tattoo Artists - 10% to 20%, depending on the difficulty and amount of work performed.
Movers - $10 to $20 per mover, depending on the amount of work necessary.
Tow Truck Operators - $3 to $5 per car towed, even if it's covered by AAA.
