First let me say your new avatar is very pretty.
Ok, so I wondered about this because it sounds unlike SLE to dismiss praise unless they found it demeaning in some way. They kind of eat it up if you do it the right way. I just talked to an SLE and told him this as a hypothetical and asked why he would not respond positively to someone saying what you said.
He said the reasons he might not take it well would be tone of voice and whether or not he liked the person to begin with. Also he confirmed that he would not respond well if he thought it was demeaning calling him a phone guy if his skill set was above that. I asked him if that meant he would feel like his rank was lowered and he said yes. I don't know why I asked that but wasn't surprised by his answer.
