stuck doesn't mean twiddling your thumbs wondering what to do next - i'd certainly expect someone to ask if they were in that situation. No, stuck can often only be observed by looking in, the person or team may think they are doing useful stuff, but someone coming to it fresh can see that they have missed something obvious, hence why recreating the problem seems to be impossible, or why the fix seems very involved. So a standup can allow you to see that someone is stuck, even when they don't realise it themselves.
