Dear Manager,

I hope this email finds you well. I am writing to inquire about a bag that I believe I left at your restaurant yesterday after having dinner with my friends.

Firstly, we should take into account the importance of locating the bag. It is a small brown leather shoulder bag .

Secondly, considering the potential location of the bag, it is expected to consider several reasons, including my wallet, house keys, and a book are inside my bag.

Furthermore, the bag should not be neglected, as it can be helpful for our life, community and environment

I hope to hear from you soon.

Kind regards,

Mary Ye
