adjective
perfunctory
per-FUNGK-tuh-ree/pərˈfʌŋktəri/
Done as a routine duty with little care or interest.
The receptionist gives each form a perfunctory stamp while looking away.

Etymology
The roots suggest performing a task just to get through it. The Latin adjective already described someone careless or negligent, connecting mere completion of a duty with doing it without interest.
In context
the way he held on a beat longer than a perfunctory hug requires I have held this person through enough genuine moments in his life to know the difference between a performance and the real thing
