Confusing break room at work

Before I started my shift as a cashier at a retail store, I went into the break room. The tables were arranged differently than when I worked on Saturday and I had to adjust to it. It felt strange to me. I know that this change happens each year before Christmas. It will take me some time to feel comfortable in this room, but I know that eventually I will. I just hate how changes in my environment affects me and how it makes me feel. I wished that this wasn't so difficult for me but unfortunately, I can't change that. This might explain why I never change the furniture arrangement in my apartment.
