關於英文時態的問題想請教下大家

I stayed at Apple Store on 24th March 2014. I arrived at the store at 5:00pm. The store was big. There were many people in the store. Firstly, I went to Toy Section. A man who was tall managed the section. There were different kinds of toys in the section. I bought three toys. I paid $200 for them. Then I went to Vegetable Section. There were different kinds of vegetables in the section. I bought some vegetables. I left the store at 5:50pm.

小弟想問問大家以上篇文章句子既tenses 有無錯。間store 係宜家lee 一刻係大，咁
"The store was big."用past tense 有無錯。
