I'm in a slight tiff with my GM and some of my party members where I bought a bottle of Whiskey, and in one npc encounter decided to give a glass to said npc.
My gm ruled it as the entire bottle is "consumed", effectively making me lose the entire bottle of whiskey. Citing that there were no bottle caps invented at that time.
I am on the side of it not being consumed entirely but handled like charges in a wand. (Peliminary google search finds the average bottle of whiskey to be 25oz and a whiskey glass being 2oz). Cork as a stopper has been invented since 3000BC, so I don't see why it should even be used as an excuse.
My question now is, how do you handle food and drink consumption in your campaigns? Are there any official ruling on this matter?
Feedback and answers are much appreciated.
