Today out for lunch with DH and FIL. FIL has his food and DH had ordered a starter for he and I to share (halloumi on flatbread). So we're both tucking in with our knives and forks, then DH asks FIL if he wants to try. So FIL starts also tucking in, using same knife and fork he's been eating with. At that point I stopped eating the starter as tbh sharing food like that make me wants to vom, added to which FIL has clearly got a cold. I didn't say anything, just said I didn't want any more.
Afterwards we went to a beer bottle place for a drink - DH and FIL had the same, and I had a fruit beer. DH asked me if I wanted to try his, and he also tried mine. DH then asks FIL if he wants to try my beer - before I can blink FIL then drinks from my glass. I was pretty pissed off at this point and must have pulled a face, also said something like "really, is this a communal glass?". DH then offers to get me a new glass and goes to get me one.
AIBU to expect not to have to make this point and not to want to share germs with FIL?
