Dear Management and Drivers of SarBus S.A.,
I am a regular user of your service and would like to thank you for the innovations you have introduced regarding the flexibility of the timetable for your A3 service (Cerdanyola-Barcelona-Cerdanyola).
Firstly, I'd like to thank you for the way your morning service operates a 'grace period' of fifteen minutes, meaning that should I accidentally leave the house late, I can be sure that your bus will not have arrived yet, and that I arrive to work only ten minutes late. Naturally, I always leave the house on time but that doesn't detract from the kindness built-in to your service's flexibility.
But it is the marvel of the evening route to which I must pay my highest homage. Each evening, your A3 service runs with a net time gain of fifteen minutes, meaning that if I leave work fifteen minutes early (assuming I wasn't ten minutes late, of course), I can get home fifteen minutes early! Of course, I leave work on time so I can't really benefit from this wonder of hyper-efficiency and frequently I need to await the arrival of the next 'earlybird' service, often standing at the bus stop for a full forty minutes (time I consider well spent, as it offers me a unique opportunity to dwell on the strength of emotion I feel for your illustrious Sociedad - a feeling only enhanced by the days you operate the super-earlybird service, which allows me to observe traffic patterns on Avinguda Meridiana for up to fifty minutes).
Ladies and gentlemen of SarBus S.A., I salute your dogged pursuit of the passenger's happiness as well as your understanding that as a bus passenger, I really do have little else to do with my time (well, there's shopping for food and seeing my wife but those aren't exactly priorities).
P.S. – as the winter approaches, may I recommend a further randomisation of your timetables: it really keeps me on my toes!
