A good doorman:

• Greets people he knows he knows.
• Helps strangers with no hesitation.
• Asks “How was your day?” to anyone who might want to be asked.
• Smiles.
• Appreciates his job.
• Appreciates you.
• Moves around during work.
• Talks with hand gestures.
• Lends a hand.
• Keeps secrets.
• Talks to the mailman.
• Likes dogs.
• Dresses well.
• Laughs a lot.
• Shows patience.
• Plays on your team.
• Cares.

Alas, not all doormen are good doormen.

Might as well lead by example.
