girls' loo(boys too must know!!)it's serious

it's horrid...in the past it was only the stink that tormented us...but now...add to it..the visual torment we, all loo-goers encounter everyday. Some honest soul in the dept regularly purges herself of all bodily sins(and wastes-- solid, semi-solid and liquid) and never bothers to wash them off the white tiled floor!! And wait...there's more...a door without a latch...so everytime a girl has to respond to Nature's call, she has to get another girl so that latter locks the door from outside and faithfully guards it with her might till the unfortunate loo-goer is done with her job; Or else one has to rush to the other loos on the other floors even if she has an important lecture to attend and she is late!! So the conclusion is: either the one who commits such nuisance in the girls' loo is illiterate, or the photocopied posters, with such threatening words, so carefully glued to the dirty door, are absolutely mute...and we remain passive onlookers/loogoers...
