Last weekend my DP had his friend and friend's wife over for dinner. They brought a bottle of wine with them and gave it to Mr on arrival. I thought this was a "gift for the host" type thing and said thank you. On offering a drink I then offered from the selection I'd bought (red, whites, soft drink etc).
This morning a mutual friend asked how the night went and mentioned the wife had commented to her (mutual friend) that they were unhappy I didn't offer the wine the brought.
Was this a faux pas on my part? It would have felt odd to offer someone their own gift back. Apparently they were both quite miffed but neither said anything at the time.
