This was kind of a shocking revelation for me in my late 20's--one of those things that made me realize how stupid I was heh. But I'd not eaten at fast food for years when I was closing in on 30, except maybe something like 5 guys. But my wife and I'd just moved into our new house, really nice neighborhood and we had nothing set up so I went to grab just some McDonalds, because fuck it.
I was shocked that the burgers were actually a little juicy, the fries were really crisp and it was...okay. I mean its still McDonalds, but it wasn't bad. A few weeks later I was in the city and decided to try it again--absolute fucking garbage, the burgers were dry as shit and old, the fries were soggy and unsalted, even the fucking soda was flat.
Made me realize that part of the reason fast food began tasting like garbage when I got older wasn't just because my tastes had changed, but that I'd moved into the city and the employees at all the places were dog shit.
