Not sure how they think this won’t upset customers. I assume most customers won’t know there is a surge until they get to see the menu board. By the time they see it they will have already gotten in line. So they either get out of line or decide to pay. Either way I am sure they are going to leave upset. The only customers that won’t be upset are the ones that want to pay more for the same food or didn’t notice. The latter will be upset if they ever realize what happened.

I have one and it works well. Vacuum and moping in one machine that costs a lot less than the irobot equivalent. You can also load it with Valetudo (open source robot vacuum firmware)

I use unifi. I have their dream machine (router/firewall/vpn) a POE switch, two access points, 5 cameras and their doorbell. I rarely have any issues.

Consumers are all about consistency. You can have a worse product as long as it is consistent every time. Ordering process being consistent is also important. That is partially why Starbucks pushes their terminology. The terminology also creates a feeling of being in a group and makes it more difficult to order at other places. Then add in gamified reward programs and a good phone app. Starbucks makes it difficult for local places to compete even with a better overall product.
