See the way I look at it is, the question of what sides you want is part of the handshake specified by the protocol. You order your main dish, and then the server confirms that you ordered correctly by asking what sides you want. If you expected to be asked about sides and the server fails to confirm, then you need to engage in error correction. "Did that come with sides?" "Oh you wanted the full meal, not the a la cart."

Man what the fuck is this thing in the US? Why don't they have defaults? Like if I order a cheeseburger I want the conversation to end there. I don't want the cashier to ask me if I want the normal cheese or the smoked one or the whatever the fuck they have available. And then if I want the normal fries or the country or or wtf. If I wanted an other-than-the-default I should had said it by myself. Or even worse once I was asked "which kind of cheese would you like in your cheeseburger?" Wtf sorry madam I didn't study your catalog yesterday while at home to know in advance which kinds of cheese you have in your restaurant in which I come for my first time ever. I just want a fucking default cheeseburger, not to discuss with you about it for 5 minutes
