I'm upset with a restaurant's owner for sending free beers and popsicles to my boyfriend whenever he orders delivery food
Does that restaurant have a motive to send free stuff to your boyfriend?
The owner is a friend of mine. He sent the stuff to make me happy.
It sounds like the owner is just trying to do something nice, and probably meant for you to get these free gifts.  You shouldn't be jealous just because your boyfriend is getting something nice as well.
No, the owner wants to have sex with me. He's trying to swoop me.
It is not nice that he is trying to sleep with you but you could just talk to your boyfriend about what is going on. If you get jealous instead when it is not his fault, he will be hurt.
