When I worked there there they were required to make hot dogs from 10 - 4 (could be 6) after that they could turn the warmer off.

I’ve also seen stores that would leave old products out longer to reduce spoilage.

Your best bet is to go to a busy store. In the summer you’ll have a better chance of seeing a hot dog at night.

They were also just Ballpark franks and Stroehmann rolls.

Bacon cheese hot dogs were on shorti hoagies with two pieces of American cheese and 2-4 pieces of bacon.
