Which is correct?

Question

One: He works at 7-11.
Two: He works at a 7-11.
Three: He works at the 7-11.

Answer 1

All three are correct, depending on the situation.

1: very informal.
2: The store is not specified; it could be any 7-11.
3: the store is specified; the listener knows which 7-11 is meant.

Answer 2

They are all correct if they are spoken in the right context. For instance, He works at 7-11, would refer to someone working for the company 7-11 and does not necessary mean he works in a particular 7-11 store. He works at a 7-11, is a statement making it clear that he works at a 7-11 store but not specifying which store. He works at the 7-11, can only be correct if the people being communicated to know of only one 7-11 store in a specified area and therefore know which specific store the communicator is speaking of.

Answer 3

Either two or three would be correct. You could just say "He works for 7-11"

Answer 4

the no. 1

Answer 5

Actually, a quick glance at their website shows me that you would phrase it much like this, "at your participating neighborhood 7-Eleven®" (copied from a promotional blurb about a new product, the "Take-Home Monterey Jack and Chicken filled 7-Eleven Go-Go Taquitos™ snacks")

Answer 6

It depends...
They're all correct but could be interpreted with subtle differences.

One - he works for the company, not necessarily at a particular store
Two - he works at a store, (unspecified).
Three - he works at the local store.

Answer 7

the first one

Answer 8

All are correct if he works at a convenience store.

Answer 9

All are good.
