Save yourself an embarrassing moment with the NiceCritic.com website, which can anonymously tell that co-worker to wash their hands before they leave the bathroom, or at least stop trying to shake your hand. Using the site is as simple as choosing between one of their pre-written messages. Unlike the similar previously mentioned Annoying Coworker site, there's no option to create your own message, but they do cover a wide variety of topics for office as well as personal situations. Add in your recipient's name and email address, and the message arrives in their inbox. It's worth noting that the site is a little slow, and likely to get slower under the "Lifehacker effect," at least for today. Have an awkward co-worker moment you're just dying to tell somebody? Is Milton playing the radio at an unreasonable level? Share it in the comments—just don't use your real name!
