A greeting is not a failed answer (V-663)

classifyTurnRole read "спасибо" and "привет" as answers to whatever was
parked, so she re-asked "В какой день?" at a man saying thank you and
spent one of three attempts doing it. That attempt is a bound meant to end
the ride, so the pleasantry both produced the worst reply in the corpus and
paid for the privilege.

They are asides now: answered as themselves, the question resumed on the
tail, no attempt spent, one ride counted.

The set is a new closed lexicon entry, matched as WHOLE utterances. Every
token rule tried was wrong on something. "вечер" answers "это утра или
вечера?" and "нет" answers a confirm, so anything that could fill a slot
stays out. The control words stay out too, because isCancel owns them.
