Would you prefer if he had treated him like a loser? He didn't look down on him, the guy asked the PM about business, so the PM took that as a conversation starter and asked him about business. The guy said he was homeless, but then said he'd like to get into business and finance but had survive christmas first

Just because someone's homeless doesn't mean they have no skill, talent or dreams beyond getting fed in a soup kitchen. His treatment of the guy was actually very good, in contrast to those who tried to belittle the PM and by implication the homeless person he had a chat with.
