Missing white sheets, almost brand new!

I accidentally left a set of sheets including several long pillowcases for one of the Airbnbs I clean in town at the laundromat last Thursday. I was out of town over weekend so couldn’t go back to pick them up. Folks at the laundry said they folded them in a bundle and put on top of heater in main area. They were taken by someone maybe thinking they were up for grabs over the weekend and I’d be so grateful if they could be returned to me or dropped off with folks at the laundry during the day when they are there. Thanks so much!
