“So if you are on an airplane and need a coffee, since there is no other way to get a coffee it would be muttar to drink it.”
What does “need a coffee” mean?
Would the same apply if I “needed a hamburger” and the only one available had a questionable hashgacha?
(I’m not challenging R’ Heinemann or the Noda B’Yehuda, I’m just trying to understand the reasoning)
