“While conducting research on the physiology of facial expressions in the mid-19th century, French physician Guillaume Duchenne identified two distinct types of smiles. A Duchenne smile involves contraction of both the zygomatic major muscle (which raises the corners of the mouth) and the orbicularis oculi muscle (which raises the cheeks and forms crow’s feet around the eyes). A non-Duchenne smile involves only the zygomatic major muscle. [...]
The Pan-Am smile, also known as the Botox smile, is the name given to a ‘fake smile’, in which only the zygomatic major muscle is voluntarily contracted to show politeness. “

If you still have the Pan Am smile after a couple of meetings, most probably you are talking to a wrong partner. A common business cannot be managed for long with fake smiles.
