I had an old pair of shorts that were stored outside that I forgot were there.
A few years ago I came home wet from the rain, drunk. I took them off forgetting I had money in the pocket.
I found the shorts the other day, found I had a couple of 100's and 1, 500 baht note soiled, mildew and very poor condition, part of the notes were perished.
I took them to my local Kasikorn bank, the teller exchanged them for crispy new notes
