Actually, it depends a bit. If you're feeling particularly frustrated you might be tempted to 'yell' at your chatbot, but that won't actually get you any results. So in the end you reset and try to solve your problem (relatively) politely.
And personally, someone who gives me clear and solid instructions beats someone who beats around the bush and then yells at me any day of the week.
So in the 21st century, people are often more patient with machines than with humans.
Hence, if everyone were to people at least with as much patience and kindness as they treat machines, I think it would be an improvement!
