You use this phrase when the action you're describing seems easy, simple, fast, unimportant, or unexciting:

I just googled "new york florist" and that was the first shop that came up, so I called them.

A: What did you do this weekend?

B: I just sat at home and watched T.V.

blindly accept (something)

"Blindly accepting" something means agreeing to it without finding out the details, without thinking about it carefully, and without any argument or debate.

For example, some people "blindly accept" any information that they read in the newspaper: they assume that all of the news stories are true.

This is a negative phrase. We usually say that people should not "blindly accept" things that they hear.
