except that in that case, he has the option of drinking coffee both before and afterwards (is he that addicted that he needs to drink coffee every hour?) In terms of feeling required to order something at the meeting, don’t they serve Coke there? And if not, he can just tell them that he can’t order anything for Kashrus reasons. It shouldn’t be a big deal, I would think.
Unless he was travelling beforehand and t/f couldn’t get a coffee, but in that case, he would have the din of a traveller anyhow.
It really does seem to me (as I mentioned previously) that halacha in general gives exceptions for travelers in many instances. (I’m not saying there can’t be other possible b’dieved situations, I just think they would be rare).
