i say maybe 6 times a year, but it's rather hard to count. in my town i have no mcdonald's burger kings or something like that, so i can eat there only during my holidays, visits to other cities near me or during school trips. but i don't really fancy it.
My school is right next to a Dairy Queen and a cafe. The cafe is far out of my price range for a daily lunch, and the school cafeteria doesn't make a lot of good stuff, so I have a burger usually 2 times a week, sometimes three if I don't feel like pizza from the cafe or a kids meal/ don't have the extra money. It isn't healthy, but I work out and usually split the burger with a friend cause I hate burgers. It's just cheap to get. (5 dollars for a 16 oz. pop, fries, and a burger with whatever toppings you want, but cheese is extra)
The only reason i ever ate nasty burgers was because that was what my mom took me to eat, and she didn't really care if i liked it or not and she wasn't about to cook for me... So when I learned how to cook, and refused my mom to feed me that kind of food, i started cooking food for my self and not eat that crap. SOOO, I haven't eaten fast food for about 5-6 years.
