Interesting question. 
 
I think most mormons would be fine if you drank coffee/tea in your own home. Given that coffee is such a fixture at work, restaurants, etc - most mormons would not have an issue with it. 
 
As far as alcohol - that might be a different issue. I think more mormons would be uncomfortable with lots of alcohol around - esp beer and liquor. I know I would, but if the host felt strongly about it (having a beer or wine) then I think most mormons would tolerate - esp since it's the host's home. 
 
But it really comes down to the individual. Me? Coffee/tea - no big deal. Alcohol? Yeah, it would bother me a bit. 
 
What do other members think?

Thanks Jett for the response.  
 
We would certainly not plan to consume any alcoholic beverages while our houseguests are here, we just wanted to know if we needed to put all evidence of any wine/beer/etc completely out of sight so that they will not feel uncomfortable. i.e. I have a wine rack with a couple of bottles in it, as well as under-cabinet rack for wine glasses. 
 
Thanks again for your response! 
 
Take care,

I personally expect no one to change there lifestyle on my behalf. I am completely fine with non-member friends and family drinking alcohol or coffee/tea for two reasons.  
 
1) My faith is my choice not theirs.  
 
2) Jesus Christ taught us to love each other and never judge for only he was worth of judging mankind.  
 
I live my like as I have chosen to and I expect everyone else to do the same. We are given this life as a time to choose what to do and why we wish to do it.  
 
For me to expect/demand someone else to limit there chosen lifestyle because of me is a huge insult and near sacrilegious for me.  
 
This is what Lucifer wanted to happen he would take our choice from us and force us to follow God. This plan was rejected and I personally feel that it is the greatest sin to try and force others to give up there God given right to choose.  
 
I know that out of respect there people will refrain from consuming alcohol. coffee, tea with there Mormon friends, and this is a deep sign of love and sacrifice to willingly give up something your desire in respect for a friend! 
 
Thank you Katrina for your excellent question and I hope that my answer helped you!
