Look, I've tried to add a legitimate additional usage for this word. In common culture today, the word "always" is being used as an intimate form of "you're welcome." I've witnessed that amongst at least a few married couples.
What is the problem in adding this here?
"any time" would be the interjection between friends. "always" would be the interjection between lovers or spouses.

May I have your permission to add it now?
I'll assume silence to be assent.
