Two completely unrelated questions:
1. Is there any kashrus issue with ordering salmon sashimi (only fish, no rice or seasoning) from a non-kosher restaurant, assuming that: (i) I was the fish before eating, and (ii) it's delivered to my office so there is no ma'aras ayin issue?
2. Is there any issue with purposely melting ice on Shabbos, either by rubbing it, pouring salt on it, etc?
Thanks!
