I too have my humi in my living room, and the humi draws a lot of attention, I hate all the questions, and the ultimate purpose is to mooch a cigar(that's why I always keep a bundle of Fumas nearby:-D) I think I want to move it to my spare room.
My cabinet has solid wood doors so it looks like a giant armoire( 88" high by 51" wide by 29" deep) that sits in my living room. The only people who get to look inside are my cigar smoking friends.
It's hard to miss my Avallo cabinet. If a guest doesn't smoke cigars and ask questions, I simply just say its for my cigars and end the conversation there. I only talk about my cigars with other cigar smokers which always leads to a pleasurable time sharing a smoke together.
It is in my bedroom closet so nobody better see it or they have some explaining to do.
I have been to somebody's office and it seems to be the focal point of his office. A great big glass doored cabinet about 4 feet high. That would have to spark many questions. I do believe he has moved it home by now however.
