I love burgers but I don't get to have them anymore from anywhere because costs skyrocketed and my income didn't. McDonald's even stopped being affordable a while ago. In Canada the price of a McDouble, at least last time I checked near me, was $4. For a McDouble.
You can get a stack of burger patties from stores usually for like 10-12 bucks then cook one for a burger in your broiler if you got one, 15 min, flip once, throw some vegs as a side, yummay!!
Tbf the other ones still only really control temperature, it just controls it automatically in some way. If you can set the temperature to a little above boiling maybe that would be like steam?
Just FYI. If you use the app, you can get 2 mcdoubles and a medium fry for just over $4. It's the only place I will still get fast food because they actually have prices similar to they used to in the app.
Remember, if you are getting something for free (including a discount) in exchange for using an app, you're paying for that in data.
Some people don't care about that, lots of people care an awful lot about that. Sure you'll get a McDouble for cheaper but you'll also be receiving scam phone calls every day for the rest of your life as McDonald's sells your personal data to anyone who bids for it.
