Can you please explain your thought process in how exactly does a pair of people walking and an [or] operator followed by one translate into "once" in "I am only going to tell you once"?
If this was not a virtual environment, I would grab you by your clothing and not let you leave until you do.
Edit: I guess the people are going somewhere, so that explains the going part but not the [or].
Edit2: when the going is in the speech bubble and not before the person telling, I understand it to follow the telling part. As in "I am (only) telling you to go once".
