Ive got to say "well done" to her.
I dont eat fast food (when cutting ) and i dont like Mc D's really as a company but what i hate the most are people who say things like :
"Mc D's made me fat so i'm going to sue them"
What this lady has done is shown that you CANT sue a fast food chain for making you fat, because if your sensible you CAN eat their food and lose/maintain your wieght.
If you eat badly your have noone to blame but yourself.
