How many minutes of active work, though? Presumably OPs 13 minute wait time involves about 30 seconds of work and 12 1/2 minutes of doing whatever they feel like.
(in any case let’s be honest, you’re both optimising for very different parameters. Which is fine!)
Do you order anything besides coffee? Maybe I'm misunderstanding, but why would you wait 13 minutes for someone to drop off $1 of distinctly average coffee?
(I say this as someone who has ordered McDonald's through DoorDash before.)
