OK eye in the sky, granted that they might want him to do a few stop and go's to practice and demonstrate continued competence in soft/short field operations, but that should be about 20 minutes, what about the rest of the full check they put him through ?
If its his own (partially) aircraft and not an ANO requirement, just an airfield specific requirement then focus on the reason and check that. Anything more is verging on "golf club mentality" IMO.
