What's the current thinking on 'thank you' emails? Imagine the following common scenario, I email a work colleague asking them to do a small task, such as send someone else a document that I don't have easy access to. They email me back later stating it's done. Do I now send a 'thank you' email? The courtesy side of me says yes but on the other hand I myself sometimes get mildly annoyed by receiving an email that simply says 'thanks'. So do I show my appreciation and waste their time, albeit only a few seconds, or not?
Any views?
