If you’re wondering how much tipping you should be doing this holiday season, Zagat has just the infographic for you (pictured below).

The averages, Zagat (recently acquired by Google) says, are based on results from their 2011 holiday tipping survey, which it ran a couple weeks ago.

“And, most of you are giving money to those you plan to tip, a cash gift ranked above a gift certificate, bottle of wine or baked goods as the number one lay out to thank the folks who serve you throughout the year,” Zagat’s James Mulcahy says. “But, you won’t be stuffing a little more into their envelope – a 79% majority of survey respondents said that they will tip the same as last year, with only 15% saying that they will tip more. “

What do you think of the results? Agree? Disagree?
