I have had this issue for years, in several companies and with many people.
So my table is at the end of a row and all people who walk behind me and then turn (following the table corner) almost always give one annoying knock on the table.
They literally give it a small knock with one or two fingers as they are passing by, as if using the table as a pivot point. There is no intent to it. It's unconscious but quite a few people do it.
I know it is not directed at me and I have nothing against these people but it is so annoying and I am not sure how to prevent the behavior. I have asked the guy next to me not to do that but even then he sometimes forget about it. It's as if there is this invisible force that pushes people to do it.
Has anybody experienced the same thing ? Am I being over sensitive ? How do you prevent people from doing that ? Maybe by putting something on the table, because I know that telling people after the fact does not work and make me look like some sort of a pyscho...
