A: Let's go out for dinner.
B: Ok, this time you be my guest.
Why does the sentence above not write as 'this time you are/will be my guest'? The pronoun YOU is the second person, so its linking verb should be 'are'. If its copula is 'be', there must be an auxiliary or modal verb before it, such as WILL, DO, DID, CAN etc., right?
PS: If you find any errors in my English, would you mind correcting me, please. Thanks a lot!
Q - Can I read/borrow that newspaper that you just put down, if you're not reading it?
A - Be my guest.
It means "Of course, go ahead".
In the example given, I would say
- Let's go out for dinner!
- Yes, but this time you will be my guest.
The use of "this time" suggests that perhaps at some point in the past, the first speaker took the second speaker out for a meal and paid for everything and now he wants to return the favour.
