Not an unusual request prior to T/O on major commercial airlines with light pax load. I do as they request, then usually have them come back after wheels up and tell me to sit where I wish given the light pax load.

When "Im" drivin' the plane, we always do what I want/ask.
Anyway on the lighter side....always, always obey a "position and hold" or in your case, a "re-position and sit" order when around aircraft and aerodomes...lol
