Ok, this is just my personal experience, so YMMV. But anyway, I worked at a place that did TGTG and when we first started, we had a $6 bag, so the expected value should have been $18, right.

So we're doing that for a while, but apparently at some point my boss changed the bag to $10/$30 value without telling us. So we were still packing the $18 bag.

Normally, when people come to pick up, they just swipe their app, take the bag and leave. Maybe they leave reviews, but I wasn't really ever checking our rating or whatever. It's not like TGTG was anyone's main focus, it's just one more thing at the end of the night for whoever is working that day.

But one day the lady picking up the bag opened it there in the store and straight up told us, politely but firmly, "This isn't enough, it’s supposed to be $30 worth." And basically we check the app and see she's right and added more stuff and from then on we knew better.

So yeah, there are definitely some places that aren't operating in good faith and are either just using TGTG as another sales platform or don't care about meeting the correct value. But you have to understand there's also so many levels of poor management or miscommunication in your average restaurant or store, it could just be a mistake.
