Depends where you fly and who owns the glider. The pilot doesn't always
own the glider, the pilot doesn't always bring all his friends every
time he flies (sometimes it's just the crew at the gliderport), the
gliderport doesn't close up at night until everyone is back, and the
business generally wants to handle retrieval of their own gliders if
disassembly and trailering is required.

Where I live and fly, glider clubs work that way: I retrieve you, and
you retrieve me, and nobody leaves until it's clear that everybody has
landed safely. But maybe such things work differently in the USA.
