Similar-ish thing happened to me, stepped outside for a bit. Came back and the owner/manager had taken my clothes out of the washer, mixed it in with other people’s clothes he had also taken out of washers, and it was drying in several machines all over the Laundromat. I asked other customers what happened, started having to stop and pick through several dryers to recover maybe half of my clothes as the rest had virtually disappeared.

Yelled at the owner manager as my clothes had maybe been sitting finished in a washing machine for an additional five minutes at most. He blamed me as if it was my fault for not immediately removing my laundry when they were done.
