Having waited outdoors in sub-freezing temperatures with my child to receive an autograph from Tom Hanks years ago when he was filming in my neighborhood, only to receive a snarky reply to my greeting, I would say "not really." And secondly, since she is known for her biting sarcasm, "probably not." Therefore it came as a very pleasant bonus.
Only an idiot would bite the hand that feeds it!
Therefore it came as a very pleasant bonus.
Now that's weird! Get out more. Comparing Ann to Tom Hanks is weird, also. Take her off the pedestal.
Well, then, we differ. If I paid good money for a book, stood in line for an autograph, and got "biting sarcasm" (read: rudeness) in return, the book would get tossed in her lap and a refund demanded.
