Ewww those pics make me wanna puke.
I don't know if you've ever seen any of those shows on the foodnetwork ( like "Unwrapped") on food advertising, but they go through a LOT of trouble to make those products look that good.
For example, they never use actual ice in drinks, they use like...a chemical or gelatinous mess...they use like...red hot iron rods to make grill marks on burgers, they glue individual sesame seeds onto buns, they use an eye dropper to add 'juiciness' to burger meat...
And really, irl, if people who WORK at fast food places took a little pride in their job...hell, just even DID their jobs right, it wouldn't look like chewed up spit out vomit.
I know, I used to work at KFC.
