This sentence was found among the subtitles to an episode of Die Chefin:
Sie ist vor drei Tagen bei mir im Club aufgetaucht.
What is difference in meaning with the sentence without the "bei mir"?
Sie ist vor drei Tagen im Club aufgetaucht.
Does it indicate "she was with me", or "while I was there in the club", or that it was "to me that she turned up", or that it was "in my club" that she turned up? The context of the story in which this sentence appears does not assist in distinguishing among these possibilities. Here is another example of this usage from the same story:
Er war bei uns am See.
I think this means, "He was with us at the lake," because the story makes it clear that it is not their lake, in the sense of ownership -- although it still could be a lake they frequently visit. But could this also mean, "He was at our lake," if the context allowed? Here is another one in a different episode (the same writer):
Er ist neu bei uns im Team.
