Flip creator gets into the grilled cheese business, Sequoia invests

Quadcopter are very fast and can go very far before they lose power. And a single sandwich is not a very heavy load.

If you are outdoors and can give it your GPS coordinates, a single restaurant/quadcopter port, could serve a very large area.

e.g. sender logs a job online (& provides payment details), sender prints a barcode sticker, sender drops off package with the building doorman/concierge and/or walks to designated quadcopter landing zone adjacent building, outgoing package scanned and loaded onto quad-copter, quad-copter delivers package to recipient's landing zone, quad-copter/system sends notification to recipient to advise that package has been delivered, recipient goes to quad-copter landing zone to collect package, recipient scans barcode or provides electronic signature to acknowledge receipt.

Terms & Conditions: Anyone who implements this idea (or minor variation) must give hook and I a $1 royalty each for every job logged ;)

I think there's an ad-hoc, informally specified set of standards for when a problem is "big enough" that people will pay to have it solved. What you're looking for is something within that range where you can out-executing the competition. Searching for "the biggest problem" oversatisfies the first half of that proposition at the expense of the second.

All that said, I find little inconvenience in the current fast food ordering process. Often there is a language barrier, but a combination of numbered meals and ambivalence towards picking off what I don't want solves that issue.

Possibly the restaurants could find value in making the experience "good enough" to keep me from going down the street and paying more at $fancy_restaurant where ordering is (relatively) hassle-free? I'm not convinced that can be done via phone in the lowest-common-denominator fashion of fast food.

On their end their software computes an estimated arrival time allowing them to precisely time cooking to be fresh and ready for you to eat when you arrive.

I would LOVE to see a Starbucks mobile app allowing me to do the same thing, so when I get to the store I could pick up my drink and walk out. In fact it would amaze me if Starbucks don't offer this in the next 18 months, given their recent steps into mobile applications (though, annoyingly for me, they test everything in the US first, so more like 3+ years until it will come to the UK).

It's even got a main character, an interesting plot, and a twist ending!
