Probably not necessary. Hot dog cart vendors are able to increase profits with simple things like charging $1-$2 for a bottle of water. Which seems to outsell all other beverages in the summer time.
The Costco I went to had fountain beverages at the hotdog counter. A lot of potential profit right there. Because if they didn’t have the cheap hotdog I wouldn’t even visit the counter, where I’m likely to also order a drink.
I think you can make a profit selling a $1.50 hotdog. Wholesale prices for a quarter pound sausage are around 60 cents. Even lower for the smaller wieners. If you ignore the costs for the building and property as Costco already has a building, then they’re way ahead of the game, they even have advantages over a simple hotdog cart.
