Coffee Machine Cuisine
We'd had a discussion a while back about how to cook for yourself while on the road. I'm not sure whether this is a helpful addition (so many things to make in a coffee pot!) or a bad thing (other, slightly demented travelers may have also been cooking with the hotel coffee pot!), but it's definitely funny: http://www.theatlantic.com/health/arc...
Um, this is a gag. The article, the blog, the idea - are an elaborate joke with instructions intended to be read, not followed.
Which is not to say that someone couldn't treif up your hotel room coffee maker, or that, as Gila suggests, a hungry kosher traveler mightn't , say, heat instant noodles with the hot water. Just, people aren't actually doing this.
Of course, posters on this board are in a special category of people who do regularly cook - or eat tinned food - in hotel rooms.
