On a business offering more than one service that takes a different amount of time, a caller who asked "have you got anything tomorrow?" without naming which service could be offered a time worked out against the wrong one — and then told that same time was "no longer available" once they said what they actually wanted. This only affected businesses whose services genuinely take different lengths of time; a business where every service takes the same time was never affected.
The AI now asks which service before offering a time, whenever that answer would actually change what is free.
