It's a common Indian thing to type a greeting, then wait for a response before actually getting to the point. It drives a lot of people crazy, because now we have to respond back and prompt them to tell us what they need and wait for a response, which is frequently a while later, causing a lot of interruption to what might otherwise be productive working time.

It turns a "can you send me this info" 5 minute task into a multiple interruption pain in the ass
