I was playing around on Doordash's website and I saw an am/pm (ARCO) location near me. Doing a pickup order there if one is planning on already being there for gas might be something I see people doing, if only to pick up drinks (though the typical gas station food is also listed).

Anyway, I did a scheduled pickup order for a burger place that I'm going to be near a few hours from now. Hopefully it works out okay.
