Likely, yes. Sadly, most restaurants (in the US at least) are shit, and most restaurants are using shortcuts like the "Applebee" model of glorified frozen TV dinners. Especially in wholesale supplier food deserts in the middle of nowhere where the options are fewer.

By contrast, I know of a Turkish-American-owned fast casual restaurant on University Ave in Palo Alto that spends hours every day making almost everything, including hummus and baklava, from scratch. There are only a few complicated things that aren't made from scratch ordered from Turkey from specialty Mediterranean food suppliers. The generic stuff is sourced from Sysco, local butchers, and various other suppliers. It's a lot of time and work to do things right, and it takes pride and cost to make excellent food.
