W: Have you been to the new sports centre yet?

M: Go to their fruit juice bar. They do snacks too. The staff there are really friendly and you can meet other people who go to the sports centre.
W: Which snacks do you recommend? I suppose they must be really healthy—not the kind of food I usually see you eating!

M: You did say last week that you thought I should try to eat a little more healthily.
