Dumb Dog

I was in a changing room, getting my kit off when I witness this fuckwitt's train of thought

Fuckwitt: The dress is 30% off so if it costs $100 then thats... ahh... errr... um.. err.. 9 times... add... ahhh... $30! and then that means you pay... hmmm... errr.... umm.. are... take that from that... errr... $60!
Dirtbag: $70!
IDIOT

So please, hear me out next time I rebuke your ignorant celebration when you decide to drop maths.
