> OJ must be fresh and squeezed no more than 2 hour prior

He also has no clue that it's 2 hours old or 4 hour old.

What he really wants to do is tell his guests "this was fresh squeezed, two hours old" and he will get what he paid for, just like his Maine lobster (thats probably Russian) or softshell crabs from Alaska (China), or Key lime pie (Chinese lime juice). That's how the resturant industry works, this test is useless there.
