A) I walk into a store, get a notification from google photos asking me "I see you're at store X, wouldn't you like to take some pictures?". Possibly to use as part of google maps. Thinking back I think this is when I started de-googlifying my life.
B) I get a notification from google maps asking me "you're travelling to place X soon, wouldn't you like to download an offline map, just in case you don't have connection there?" Google must have learned that because I had the plane ticket on gmail.
