You realize that you've got to enable voice ordering?
Alexa works in conjunction with an application which you can use to control the 'skills' that Alexa is allowed to exhibit. One thing you should definitely not turn on unless you can control it is the ability to order stuff (it is off by default).
I realize that this device is new to a lot of people and so now we've got to go through the 'vandalism' phase with everyone trying novel ways to screw with it but its just an interface, albeit one with outstanding voice recognition and synthesis capabilities. I'd like Alexa to be able to identify individual voices, I daresay this will come in time but its not a regular skill, because she will not only be able to personalize her replies but also we can avoid situations like this.
Incidentally, for everyone who's not seen one of these yet I should mention the 'mute' button -- you can turn her off and on at the press of a button.
