Lately, we've been doing a lot of work for different embassies of the world and I'm always amazed at the different bathing preferences each place has. So it seems to me that half of the modern world prefers NOT to use toilet paper although most religions now permit it's use. We've been ordering some specialty products from overseas and one company gave us some cool SWAG. I'm thinking about handing some out as Christmas gifts This particular model comes with AA batteries and a two speed switch.
In my effort to better understand others toilet etiquette, I found this an interesting read:
