If the question is just 5 words or 100 words you can type them in 10 sec then sure I’ll wait. But that’s not how it usually works. You see it’s the people who are least used to chat and so both type the slowest that also misunderstand the greeting protocol. Greeting is fine. Greeting and then typing for 5 minutes is not.
Also as a remote worker something that really annoys me is when someone goes “hi, got time for a question?” and then 20 minutes later “sorry someone just walked in”. Don’t do that. If you sent a hello, always pay attention at least 15 seconds and be ready to interact. Don’t ping and then go for coffee. And please ask people who walk in to wait while we finish chatting, or just tell me someone walked in you need to talk to so I can go on with work.
