同事之间一起吃顿饭可以很好的协调关系、沟通感情，比如 donald 和 debra：
donald: let's eat out, shall we?
debra: i'm broke. i've gone through my paycheck for the week already.
donald: don't worry about it. it's my treat.
debra: you're sure? you're so generous!
donald: and nice, too.
debra: so, where are you taking me?
donald: some place you've never been before. donald's kitchen.
mary: thanks for lunch. it was delicious.
