Mr. Burner, if you are in T&E service, there is nothing in your BLE or UTU Agreements that requires the carrier to make 'bargain" meals available at away-from-home terminals. The understanding in so far as the term "suitable lodging" goes, is that a "round" meal, as distinct from a burger and fries, is available 24/7.
Be mindful that the carrier is likely subsidizing the restaurant operator to stay open the 24/7 called for in your Agreement.
Albeit 30 years ago, I had to address that point once when I was in MILW Labor Relations.
