Rubyの条件分岐時のエラーについて

Question

※解決しました！

除外がうまくいかないので質問させてください。

まず今回、スクリプトで実現したいことは以下です。

• Google Place APIでレーダー検索からplace_idを取得
• place_idを元にプレイス詳細検索してjsonで別ファイルに出力
• その際に以下の不必要なデータの除外

1. shopping_mallで7 Erevenの除外
2. grocery_or_supermarketでconvenience storeに該当するものは除外
3. （convenience storeでは除外させない）
4. bankでnameにatmが含まれれば除外
5. countryがマレーシアのもの以外は除外

https://developers.google.com/places/web-service/search?hl=ja

しかし、今のスクリプトでは、

1. grocery_or_supermarketでconvenience storeに該当するものが除外
2. （convenience storeでは除外させない）

の部分がうまくいかず、convenience storeの際もcの条件を除外してしまいます。

解決方法を教えていただきたいです。
よろしくお願いします。
