I didn't know about the "Drop In" functionality or "Announce" for that matter! Thank you for pointing these out.
I'm a bit uneasy about ordering anything directly by using voice, so I'll start with just adding certain things I need to the cart first. This way I don't forget about them. However, I will still order them via my phone or computer. There is something about visually double checking what I'm spending my money on and if that is in fact what I need.
Now that you've mentioned about geeky stuff you can do with Alexa, I'm going to go on a deep dive to hunt down the Alexa skills that I'm clearly missing to make it truly personalized. I guess not many of my guest will be impressed if I ask Alexa to tell me what the weather is like. They will be impressed, however, if Alexa can tell me the when the next SpaceX launch is. Hopefully it will blow their mind as much as it would mine!
I'll keep on exploring and elevating my Alexa skills 😉
