I've noticed in my particular region of the US, there's an attempt to move them somewhat upmarket-- instead of (or in addition to) the hot-dog roller there's a food counter preparing almost edible hot foods, the drinks machines have much wider choices (10-20 sodas and 8 coffee products instead of 6 sodas and two coffees)

Guessing the plan is that as EV charging replaces petrol purchases, they can reposition into the quick-meal market.
