I've heard of using Tide as currency, as well.
Separately but similarly, I saw this awesome post recently: https://steemit.com/guns/@mattclarke/this-is-what-you-sound-like which is about "I want to know how many socks you have, how long you've owned them and how you got them." :)
Yes I remember that, it was about 1 years, maybe 2 ago.
I just read that post @mattclarke, I enjoy the sarcasm. Thanks for the comment and the link.
