Reasoning behind Muhammad SWT stopping caravan to search for his wife's necklace

I've read that once Muhammad SWT stopped an entire caravan in a desert to search her wife's lost necklace. While I understand this shows how much he loves his wife, this must have created annoyance among other Sahabas. Q1. According to islam what is the takeaway here? As a husband we should look after our wife even if it creates a discomfort to others? Q2. Muhammad SWT could also ask the caravan to move ahead and camp somewhere comfortable, while he searches for the necklace. Why didn't he do that?
