1. I was talking where it isn’t.
2. “What about the possibility of the suction of the squeeze bottles sucking in the fleishik fluid.”
To suck in you would have to keep it on the meat after you squeezed -not done -noone keeps it there that long.
“embarrass a guest (Dioraysa)who touches it to the hot-warm-cold meat.”
Why embarrass? That bottle just became Fleishik.
“or have 2 separate ones and explain to them that out of a sense of Yiras Shamayim we would not to chas vshalom mix”
An unnecessary Chumra, unless you eat your meat like YOU eat your pizza. Most people don’t eat like this, even kids, and one bottle is just fine. You pour from away the hot food a few inches and if ch’vs something touches -then it becomes either Fleishiks or Milchiks!
