Funny, as a kid I felt the opposite. Getting to eat McDonalds, or fastfood at all, was a rare treat because it was expensive. On road trips, my parents packed cold soggy sandwiches for me and my brothers. These days though, I associate McDonalds with 'no other option' and don't care for the food at all (probably because I never developed much of a taste for it in the first place?)
A little secret you can do is maximize the a-la carte menu. I will get a cheeseburger, no ketchup no mustard, add shredded lettuce, add mac sauce.
tada! you got a single patty big mac for $1.30ish. but if you're feeling cheap and this deal isn't happening anymore, you can do the same with mcdoubles.
