My DP is really into his food, makes most meals at home and even thought about being a chef when he was younger. It's a hobby.
But I'd say 60% of the time when we're out for a meal, if the server asks 'how was your meal?' he doesnt give the obligatory response.
Instead he uses it as an opportunity to moan about the carrots of the gravy or whatever and say 'it could've been more X'. I feel really embarrassed when he does this as other diners are just quietly enjoying their meals!
He stopped for a while because he knew it bothered me but he's back at it again
