After Thanksgiving BrickUnderground ran a not-un-useful guide to holiday tipping—certainly it was more helpful than the Times' anecdotal take (we don't have a car let alone a car to tip away!)—and as part of the guide they ran an informal survey to find out what people are tipping. A month later, survey says... most people this year topped out their tips at $500 or less. Granted, the survey didn't take into account the number of staff in a person's building, so you can take the results with a '91 Honda Accord full of salt. And remember, by custom you have until the end of the year to give holiday tips.
