but that person did not say he want 3+2 ADS. He might want 2+2 ADS instead. If 3+2 ADS was given to 270A, he might reject it.
270A can't used euro 1 ADS, so he might be saying euro 2 2+2 ADS. He never said anything about comfortability and maybe likes to take buses according to the bus speed performance and not like many people taking buses according to comfortability.
