So several ideas in that case:
Sneeze over the food very loud and nasty
Lick the burger and claim yours

If not feeling savage, hand him the burger and get another one or two immediately after

Maybe it’s because I have been in this situation before that I know exactly how to act haha usually a resounding NOH solves it lol. My cousins and uncles are notorious for trying to pull this shit on other people. I know how these bastards act step by step 😅 

 This is hilarious. You have a step by step manual on how to deal with “gimme dat” 😂😂😂 

 Life is a cruel mistress lol 

 I’m a predator when it comes to my plate of food. I’m willing to fight for it 🤣 

 I can understand that. Once it’s in my plate, it’s for my consumption lol 

 I don’t share, I don’t let anyone have a bit or a taste. If you didn’t like your choice of food, go ahead and other something else 💅 

 A plate of tapas or appetizers is fair game. But, my plate = my plate  💅 

 My plate = my plate 💅 

NOH. Touchy 😂 

 😂😂
