That's how it was in the US, too. Sit down anywhere, fire up the app[1], order whatever, enter the table number and they bring it over. That part of the service was consistent and worked well.

The consistency all changed with the covid shuffle.

Now, it depends on the location and their mood at the time. Sometimes, they bring the food out on a tray. Sometimes, they just dismissively put it on the counter at the front in a paper bag and walk away from it without a word. Sometimes they fill the drink for you; sometimes there's a rack of cups and an implied expectation that you just figure it out yourself; sometimes they bring over an empty cup; sometimes you have to beg them for that empty cup. It sucks.

Same with the kiosk. They have these neat table tents with numbers; they're actually BLE beacons that work with tracking hardware inside the ceiling. They help the employees to get a good idea of where you're sitting before they even leave the kitchen. But sometimes there are no table tents to be had (even in an empty restaurant), and sometimes when they do exist nobody gives a damn about them.

As systems, these things work fine. I've seen them work. But I've observed the implementation of them in recent years to have been an unmitigated mess, and this mess is clearly the result of a geographically-diverse problem with bad local-level management.

Buying a cheeseburger and a Coke at McDonald's -- which built an empire around simplicity and efficiency -- should never be an adventure or a guessing game. It should be the most straight-forward process on Earth and completely devoid of surprises.

But it isn't.

[1]: Well, within the app's limitations. I did rant about that in another comment, above.
