The location of your presentation does matter. Did your audience had to travel to get there? Was it a long journey, or something nearby? Depending on the location you may want to link or refer to it in your presentation. It will make your audience aware of where they are and link it.
It may facilitate in your audience remember what you told them. If you already link the location during your presentation it makes it easier to refer to it at a later point in time. “Remember what I told you at location xyz?”. Create a memory point by specifically linking your presentation to the location.
