How do you guys deal with "senior" devs that want to use you because they're not so "senior"???

Situation:

There's this SR Frontend developer that keeps asking me for "suggestions" to modernize the frontend.

This dev, was asked a very simple ticket involving some JS and CSS.

I had to do the JS and this dev modified a VENDOR CSS (that was all she did)

She logged 3d6h of figuring out the ticket and "doing a bunch of cross browser testing"

I logged 2 hours to see what to do and implementing the change.

Now she is asking me to join in a group so "we" can come up with a plan.

I hate how people bullshit their way up
