OK, this is probably more a life tip than a  practice management tip, but so what? There is one inexpensive item that I have at home, in my computer bag and in a desk drawer. That is a Tide to Go stick. As Ross Kodner recently pointed out at a "60 Tips" presentation, these work so well it makes you wonder about exactly what the secret formula contains. But if you drop some food on your shirt or tie at lunch, you just pull out your Tide To Go stick,  rub it on the offending stain for a moment and watch it disappear. it may not work completely every time, but it improves the matter every time. it also helps when the item goes into the wash. A great investment of $2 or $3.
