[Avodah] Office Coffee machine

[Rich, Joel]

I see, though, that washing was not invoked in the coffee-shop mug
question. So, does that mean that when RHS worries about hevel in my
case (as posted here by RJR) it is implying he would also tell you not
to use that mug -- perhaps, unless washed with nosein taam lifgam?

Also, why does RHS assume there is hevel? How much steam qualifies? The
office machine doesn't actually cause boiling. But even breathing on a
cold day makes a cloud, so does 180deg water in room temperature.

Third, but also on the "how much evaporation does it take to constitute
hevel?" question: Would there be a difference between the coffee
machine, where the cup if a few inches under the spout, with restricted
airflow between them, and the hot water spigot on the water cooler,
where you aren't likely to raise the humidity around the spigot nearly
as much?

Tir'u baTov!

-- 
Just to be clear, my report was from a general "workplace" shiur and R'
HS did not go into any detail on reasons or clarifications of differing
apparatus, just said it could be a problem (e.g. he didn't iirc mention
what kind of cup or spigot ....he had in mind)
