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?
a) What about the knife being used to cut it? maybe it has non-kosher fish/other ingredients on it and also it may be a treif knife used to cut charif things?
b) Maybe the restaurant is not so honest about not putting spices/flavors on it? Maybe they really use a treif fish instead of a kosher one...
c) Why is there no maris ayin if its delivered to your office?
2. Is there any issue with purposely melting ice on Shabbos, either by rubbing it, pouring salt on it, etc?
Thanks!
Where is the ice? in a cup of liquid?
Are you melting the ice because of worry of someone falling?
Are you adding salt for flavor?
