Dear Douche Bag,
Yeah you. the one with bling on the ass of your jeans. Not a good look on a man by the way. Sorry, I digress.
When you are at an establishment with unisex bathrooms, put the freaking seat down. And for the love of everything holy, FLUSH THE TOILET! "If it's yellow let it mellow" is only quasi appropriate if you are at your own home and not in a public restroom.
PS. I am going out on a limb here and assuming that since you didn't have the time to put the seat down or flush, you probably didn't take the time to wash your hands either.
