Bonnie overeacted in the 'Her Father's Daughter' episode?

In the episode where Sam and Bonnie stay at the hotel, and two guys come over to their rooms who (unknowingly to Bonnie) just want to get into their pants, why did Bonnie get so mad when Sam kicked them out? She is such an airhead.

I know she said that Sam was "running her life and sticking her nose into her business," but all Sam was doing was trying to protect her.

On top of that, after Sam gets kicked out of the room, she later comes back to the room and Bonnie tells Sam she kicked a guy out while she was away for the exact same reasons! The episode link is below.
