A practiced dance routine just to order a Starbucks?

At a coffee shop you get your regulars and what really blows my mind is quite a number have their own premeditated ordering procedure venturing from a specific over-rehearsed script such as spending 4 minutes wasting my time acting like they are reading the menu acting interested about other drinks before abruptly shouting "latte" or "flat white" all the way to a very much a dance routine with precision choreography.

This post is to discuss what I am calling is the "Choregraphed Ordering Procedure" the same people having the exact same behaviour and physical moves each and every single time they attend. The gait and posture is the same. The specific path of entry is the same - never from a slight off-angle. The facial expressions are the same. The hop skip is the same. The hair touch is the same.

What's going on? I am literally fascinated by it.
