Happened to me before heres my story,
I was drinking a beer once with my friends and my beer was about a quarter full and so then I went to the bathroom, when I came back it was about a little over half full but I didn't realize because I was half in the bag. So I drank all of it and still didn't realize why all my friends were snickering at me, it did have a weird taste to it but I just ignored it. By the time I got to the last drink it was REALLY bad, and then one of my friends ask why I was making a weird face on the last drink and I said it tasted weird then all my friends bursted out laughing and there was one of them that was doing jagerbombs and he had poured a bunch of jagermeister in my beer when I went to the bathroom, and I still drank it even though it tasted as bad as it was.
And so the moral of the story is to always take your drink wherever you go :)
....damn untrustworthy friends.
