I have a very old friend (known since we were 3) and she has a long term DP who is lovely but a massive, massive snob. Particuarly about wine.
We eat at their's very often, as they prefer to cook than be cooked for (but that would be another thread).
I always bring a bottle, often two, as they are heavy drinkers and I want to contribute if they are cooking for me. However, I often bring some wine, it gets opened and poured out for me and DP. Then, my friend's DP brings out a bottle from his Wine Society case, opens it and drinks just that for the evening.
Am I being unreasonable to be offended by this? My DP is livid but says there is no point in trying to bring it up.
