..or you will be sending a fine, invisible aerosol spray of faecal matter (etc!) high into the air, and it lands on your towels, toothbrushes () and in fact everything!
Saw it on TV the other night.. they used an ultra violet light to show up where the aerosol spray landed each time somebody flushed without shutting the lid. Blleeeuuughhhh...
I had read about this before so already shut the lid.. but am now making everyone obsessed about it..
Just imagine.... no.. don't! [puke emoticon]
