It's possible that if you keep failing you might need to raise your stealth skill to a sufficient level. Until that happens you can just ignore Benny and come back.

Stealth boy + sneak magazine, make sure you are behind him. Wear no armor.

Extra points if you use Maria to kill Benny point-blank with one shot. Oh, sweet irony.

I've never thought about the sweet, sweet irony of that. I don't wanna make a mess in Caesar's tent, but he does owe me this one favor.

Try hiting the take all button instead. Your almost always caught but your more likely to acquire the item.
