Today in the Boston airport, a gentleman approached me, put his bag down in the seat next to me and said, "Are you going to be here for a couple of minutes?"
Back in the day, it was not unusual to watch someone's luggage for them, even if you didn't know them, while they went to the restroom, etc. No one has asked me to watch their bag in all my travels in close to 5 years now!
My response, "Yes, but I'm not watching your bag. I have no idea who you are sir."
I hate to say it, but we do live in a different world today.
