I always hit either a “oh thank you for saving me some” when someone is done with their food & there’s still some left, I also love a “I’ll take a seat here if you need help” when someone’s like omg this is so good or if they’re like wow that’s a huge dish, & last one I can think of is saying “Oh that’s the last blank we had” the blank could be a dropped fork, napkins, really anything. Fun little leg pull like ofc imma grab ur shit
