I just cancelled my membership (was free with a credit card i already had). They offered a "free membership" for 10 months "at a $120 value" (which used to be $60 a year), however I couldn't figure out how to activate it. I can't figure out what the value is over other services/direct from restaurant. Like another poster, most of the suggestions were bad. "Do you want dairy queen?" Or "quick you can order free from K…

One of my wife's assistants likes McDonald's. A weekly reward for no products breaking in shopping when she does packaging is lunch. The cost of having McDonald's delivered is far less than the opportunity cost for her to pick it up (and obviously for us too).

I get McDonald's delivered all the time. Can't beat 13 minute delivery for coffee in the morning.

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.)

Wait, so they are actively encouraging Sybil attacks? See https://en.wikipedia.org/wiki/Sybil_attack

I think it's a coincidence. Sybil is reference to the book / movie about multiple personality disorder. Both deal with multiple personality systems.

It's a $12 minimum order where I am anyway. So you pay $12 whether you have $12 of items or not.

So, I am guessing GP has a couple egg-mcmuffins in there somewhere.

My coffee routine only takes 8 mins from whole beans to v60 pour over, most of that the kettle warming.

McDonalds is one of the most popular restaurants in all of America. Forget DD, probably 10% of America orders McDonald's every day. It's not that surprising. It probably keeps pretty well during delivery because it's designed to be under a warmer for long periods of time.

... with MUCH better-tasting coffee than e.g. McDonald's as a bonus!

I'm yet to have the 'wow' moment from any recommendation service.... Netflix, Amazon, Deliveroo... At best I get the 'meh why not'. It's obviously a hard problem to solve.

What about Youtube? Im surprised to not see them mentioned in any of the comments under yours. For all their faults, I regularly am recommended amazing(ly interesting to me) videos.
