I'm actually pretty sensitive to mold, and a few other environmental factors, so my concern is mostly about inhaling spores and ending up with the crap growing in me.
I know mold is omnipresent, but what I can't see doesn't tend to bother me. What I can does. I'm funny like that. I'm more put off by their attitude. I wasn't asking for anything for free, nor do I expect it.
I have to wonder if they actually think they're right, or if they think since they're around cigars all day that they know everything and the customers are just unknowing hacks?
When I was in Guatemala I saw the hotel had a walk in humidor with cohibas. I got excited and called for someone to let me in. I looked in the top of one of the boxes and it was covered in a carpet of blue green mold. It was ugly. I just left since I didn't speak Spanish and wouldn't have been able to tell her why I wasn't buying any. These cats speak english.
