AITA for collecting borrowed chairs while my neighbor's guests were still sitting on them?
AITA"Could you give us another hour?" my neighbor Dan texted at 7:50. "Dinner started late."
He had borrowed six folding chairs for a gathering at his flat. I'd said he could have them from four until eight, because I had six people coming for dinner at 8:30. He replied, "Eight, absolutely."
I don't have spare dining chairs. When his message came, my food was already in the oven and two of my friends were on their way. I texted that I needed the chairs back at the agreed time. He didn't answer.
At 8:10 I knocked on his door. Several guests were still sitting on my chairs. Dan came into the hallway and said, quietly, that he'd had to wait for someone whose train was delayed. He asked me to borrow chairs from another neighbor for my dinner.
I said, louder than I meant to, "No. I need the six chairs I lent you." Four people stood up, and Dan helped me carry the chairs across the hall. One guest said they hadn't known the chairs were borrowed.
My dinner went ahead on time. Dan hasn't spoken to me since. His partner says I could have waited while they finished eating or at least let him explain to the room before I started folding chairs.
I had waited ten extra minutes, and I didn't want my guests standing because his plans ran late. But I also knew walking in would be embarrassing, and I didn't give him a separate moment to ask his guests to move. AITA for collecting them when I did?
