I remember I got impatient with that game for having to wait for the milkshakes to be done, so I never lasted more than a couple of in-game days with that one! I have made milkshakes IRL for work before and even with the crappy blenders I had to work with, I feel like it didn't take as long as that game! I think Freezeria just makes it look slow because of how slow the blending animation goes.
