The model doesn't have to be like for like though. Set up a restaurant instead of a convenience store (think American diner style) and offer a discount on your charge for every $10 spent, or a similar integration.

Now you have a reason for someone to sit and spend money, and likely enough as EVs hit critical mass to justify costs. There are things to work out on speed of food vs charging times, potentially a queue and valet setup - but napkin maths it seems viable.
