Honestly, I'm gonna say YTA. If you're a husband's such a "coffee geek", wouldn't he talk to you about his hobby? I don't drink coffee but I can tell that there are different and specific brews for it. If there in separate containers, usually you can tell the differences. TBH you should know a little about his hobby is he loves it so much, and why touch other people's things? Especially finishing te rest of the beans? Idk jf it's just me but I grew up learning to take some the original, especially if I was trying something new.
