My husband and I were waiting at the carousel (approx 2-3 feet back) in SFO with our two girls directly behind us. We had many bags, boogie boards, etc. and had sort of a line up so we wouldn't clutter the carousel and could efficiently get our luggage, pass it back and go.
I turned to speak with my daughter for perhaps 10 seconds and imagine my surprise when I turned back and found a man standing directly in front of me. He turned and yelled back to his wife "Here Honey, this is a great spot". He was completely offended when I told him that it was a great spot, because it was my spot

and I'd been standing there for quite a while. He literally said "You don't own it!" I felt like I was having a conversation with a six-year-old.
My husband was furious (he's doesn't like when someone disses his wife

) but we let it drop. The man actually stood there for approx. 5 minutes until I think he felt uncomfortable enough to walk away.
