probably 3/100 at home and like 15/100 at school because the food up here blows and it can get a little messy hahahaha... but as far as wipes go it takes about 4 or 5 wipes to be clean.... oh and for all you fuckers who flush the toilet seat while your still seated DON'T DO IT... there was a special on the news a while back about some guy who got aids by flushing the toilet in public places while still seated... the water splashes up and if it's contaminated it can infect you with anything floating in the water... you can even get STDs from the toilet
