Difference between 商店 and 店舖? Can someone explain the difference between 商店 and 店舖? The dictionary differences are not clear.

1) For instance, if you want to say, "My friend works at a store in the downtown area," which would you use?

2) Are there any key differences between 商店 and 店舖?

Thanks!
商店 refers to "store" that sell goods, for example, a book store where books were sold.

店舖 refers to "commercial establishment".  A restaurant, a DVD rental store (younger generation might not had seen one ), and of course, a book store,  are all 店舖
