·  "Question tags are not independent clauses, but they do require a response, and are highly interactive. Structurally, interrogatives are abbreviated yes/no interrogatives consisting of an operator (either positive or negative) and a pronoun, which repeats the subject or substitutes for it. Question tags are attached to one of the following clause types:

• a declarative clause: It was quiet in there, wasn't it?
• an exclamative clause: How quiet it was in there, wasn't it?
• an imperative clause: Be quiet for a moment, will you?

Of these, the declarative is by far the most common."
(Angela Downing, English Grammar: A University Course. Taylor & Francis, 2006)

·  Commas with a tag question

"Place a comma between a statement and the brief question that follows it when the subject of the statement and the subject of the question is the same entity (example 1). When they have different subjects, the statement and the question must be punctuated as separate grammatical elements (example 2).

Examples

1. George was not there, was he?
2. I will never stay in that hotel again. Will you?
