For me one of the most entertaining parts of flying first class is when cookies and milk are served. You see people in suits dunking their cookies in milk, which is a priceless site. So admit it, how many of you do this?
By the way, I took it one step further yesterday, and it was totally worth it. I asked for a spoon, and separated the cookie into about a dozen pieces. I then placed them all in the milk, and after about a minute enjoyed the pure crumby, chocolaty goodness…. give it a try!
