What kind of coupons are issued?

In Japan interesting coupons were issued to revitalize this financial situation. We bought some books of discount coupon for eating issued by our city, and some books of discount coupon for shopping.

According to "my plan", we were going to use the eating discount coupon for "our" lunch outside. HOWEVER, once I gave a book to Yuki, who wanted use the coupon for his favorite ramen noodle, ---- most of books "were" used for his ramen. I don't like ramen noodle he likes. So when he goes to join his band practice, he eats his favorite ramen noodle outside. 

And, now, the books are almost finished. I imply him that after using the coupon, if you want to keep the "habit", you should pay it from your pocked money.

Well, what will he do?

We bought the eating discount for 30000yen in June, and it gave us 10000yen discount. Additionally as of now, Yuki had ramen noodle more than 20 times.
