What's the most annoying thing people do when they send messages without greeting or context on WhatsApp?

One of the most annoying things is when people send messages that are abrupt or unclear, lacking any greeting or context. For instance, receiving a message that just says "Need this ASAP" without any introduction or explanation can be frustrating. It leaves you wondering what exactly is needed and why it's urgent. Additionally, it can come across as impersonal and demanding, especially if the sender doesn't provide any context or acknowledge your previous interactions. It's generally nicer when people include a brief greeting and context to make communication smoother and more pleasant!
