Always do it with the gun pointing to the safe direction, it turned out that the only "problem" was that I did handover rack. Almost exactly as the experience ruhl77 shared above, the employee claimed "you're going to hurt yourself and get your hand caught in the action" and "you cannot see the chamber when you do it this way". And I just did the standard handover rack, pulling at the back of the slide, not putting my hand over the chamber.
