Keys to Remarkable Service

Put this up on the white board while discussing the keys to remarkable service with a group of hotel new hires...

A- Acknowledge (connect with anyone within a 10 foot range, invite a conversation with body language, eye contact, etc.)
E- Engage (greet and talk with anyone that gets close, 5 feet)
S-Surprise everyone by taking an extra step, doing something unexpected, asking a question to take the experience to a higher level, etc.

Have any to share?
