Don't leave home without it.
As I travel, I’ve been making a habit of harvesting all the little soap and toiletry items that hotels put out. A very convenient size and ideal packaging for trade goods. You have to keep your eyes out for even little opportunities like that.
I have picked up a few that way. But I don’t really travel often. beprepared.com has the small little rounds of bath soap for .20 cents each. Probably other places too. I’ve also taken regular size bars I picked up on sale, used a warmed knife and cut those into 6 pieces, sometimes 4 pieces etc.
Someone shows up, I’m not giving them a whole bar, but I’ll give em enough to help wash off some germs and be on their way. And no I won’t be giving them my drinking water to do it. lol.
Hmmmm ... not a bad idea.
I generally try to avoid those things.
That’s a different perspective.
