I've seen "refreshments" listed in coach on trans-con flights. In that case, refreshments = snack pack (currently 4 wheat crackers, smoked gouda cheese, trail mix, and a shortbread biscuit) at the beginning of the flight, and a choice from the snack basket (pretzels, cheese & crackers, humongo-biscoff, granola bar, or peanuts). I wish they'd bring back the sun chips!
