Folks as an enthusiast should understand that a bus, new or old
even, is just a bus to the common people. Going hoo-haa over a
'cameo' in your sense would sadly, return a sense of 'crazy' from
common people!
Like how sbs&tibs described earlier, it would be better if a
natural sense is maintained. It would be good to go hoo-haa (inside
yourself and not visually/aural) once in a while, but bad
impression from common folks grow when these hoo-haa are amplified.
Amplified = shouting and screaming around, telling people around
you the exact words that a certain bus cameoed on a certain
service.
Trust me, when you tell this kind of things to others, either
they would label 'crazy' straightaway or they might choose to
suspect you of being a spy on the companies. Imagine working in
office next time and suddenly someone screames "53H on service
307!" or similar.
Buses is not pop culture. People screaming after idols =/=
people screaming after buses. The latter is not a
socially-acceptable behavior (yet).
