SharePoint Site Opens in Contributor mode for Site collection Admin, Farm Admin; Farm admin unable to Delete site

Today, I am running on a weird issue. for a particular site collection in my SharePoint environment, It opens in the contributor mode, and when I tried, I’m unable to delete that site collection, Even though I’m a Farm Admin!

Huh.. After spending considerable amount of time, I figured out the issue. You know what? The Problem is: Site was locked with Read-Only access!

Once I unlocked the site, I see “Site actions” shown up, and everything turned usual.
