If I may say so I think you're misjudging someone else's opinion as a personal attack on the way you conduct yourself in a restaurant.
It wasn't and it isn't.
You're perfectly entitled to seek whatever opinion you wish from a server but I presume you respect someone else's personal preference not to.
Hey,in the scheme of things it ain't that important.
Why,even tonight,I asked a waitress trying to push me some " line-caught " cod exactly when the cod took the bait.
She didn't know and I suspect she didn't even know how to determine whether the fish was swimming in water within the last few days or caught and frozen in a net by a giant Spanish trawler off the coast of Iceland six months ago.
It's why I have no interest in their opinions.
