You’re probably right about fast food not being cheap nor fast anymore, but I don’t think this is the reason sales are down. That would imply
- more chains are experiencing the same drop; and
- this happened globally too.
Perhaps I misunderstood you, and you meant only Wendy’s and only in USA (or there’s other sources saying sales are down for other vendors and/or other countries).
What are some other reasons sales are down in the US? I’ve heard that the economy is turning K-shaped, and I imagine that’s bad news for fast food chains like Wendy’s, as a minority of rich people can only buy so much food. But this would again mean other chains experience slowdowns. So I’m not really sure
