In 2005 I was a bartender at a high-end restaurant. One night I noticed that every single person at the bar was in real estate - investors, flippers, mortgage brokers, title people, agents, landscapers, etc. At the time, I took it as a sign the top was near and a bubble was about to burst.
Fast forward... Last week, my wife and I were having a quick drink and appetizer at a higher end restaurant. We were the only ones at the bar not connected to real estate.
(yes, we go to many bars and are very social. By the time we leave, my wife will have met almost everyone at the bar )
