I returned a bunch of smart outlets I got at Home Depot after I got fed up with waiting for the app to launch just to turn a light on or off.
I also don’t want to have to talk to it, so switching to Home Assistant with Zigbee button remotes has made my experience so much better. And on the plus side, everything still works when the power or Internet goes out because I’ve got it on battery backup.
I think this largely depends on the system they’re using for billing. In Canada, most restaurant systems bill by seat anyway, so it’s easy to print multiple receipts or a combined one. A lot of systems in the US bill by table, so the waiter is the one who has to do all the math.
