I like fast food. It tastes good. The Whopper is tasty. The Big Mac is tasty. McDonalds fries are cracktastically good. I just don't eat it often. I know it's bad for me, so I just plain don't. Maybe once a month. But it's tasty.
Please don't take this personally, anyone here. I find it strange, though, that everyone I meet or hear from says they hate fast food, or go on about how it give you the runs or something. Yet they still make billions in sales. How can that be when nearly everyone I see says it's nasty?
Because it's easy. I hate fast food. Everything you've mentioned is tasty, in the way that tasty refers to having a taste, and so garbage and shit have flavors though you don't see me ladeling it out of the toilet, and liking the over-salted, so wet they're watery fries of McDonald's is a good reason to question your judgment on any food ever. However, when you're on a six hour road trip and are trying to get some quick food for the kids when there's still three hours to go and it's 10 at night already, you stop and get some fast food, because it's easy. I've bit the bullet and eaten McDonald's when I had to, because it was that or go hungry until we arrived at our destination at 1 or 2 in the morning when you're unlikely to get any food anyway. It's a matter of necessity.
Now apply that to running late several evenings when both parents work, or you're trying to get quick food before you arrive at work, or your shitty job only gives a 15-minute lunch break, or you just can't be arsed to make your food beforehand, or it's the end of the day and you're tired, etc., etc... Life just puts you in a position to eat crap sometimes, even when you don't want to. And it happens to a lot of people, and often.
Then there's the Happy Meal, and my sister and I pushed for that shit again and again even when we couldn't mouth down an entire carton of McDonald's McChickenTurdNuggets, because we wanted that fucking toy, dammit. It's no wonder so many kids in the U.S. are overweight.
