Grumman Aerospace sent North American Rockwell an invoice for towing the Apollo 13 Command Module back with the Lunar Module.
In response North American reminded Grumman that North American Rockwell had not received any payment for ferrying the Lunar Modules on previous trips to the moon.

Oh man I spent a long time just looking at this and reading the handwriting and trying to figure out what was being towed. At first I thought it must be a ship, but supplemental oxygen? Maybe it was a submarine mission? Maybe they had to keep something burning? Then I saw Apollo 13 and was like “oh, hmm…ohhhhhhhh.”
Damn, Grumman throwing mad shade.
