Someday my annoying habit is going to cause my death

One of my favorite habit (and annoying to many people) is insisting on implementing the rules. The previous Sunday, while I paid my fare on board the jeepney from my hometown Sogod, Cebu to Cebu City:

islesv: Here's my fare. (Handed in 40 pesos.)
driver: This is not enough. The new fare is 50 pesos.
islesv: Since when was that?
driver: Since the other Saturday.
islesv: Eh? I went home last Monday and only 40 pesos was collected from me.
driver: But we [drivers and operators] have already agreed that 50 pesos is the new fare. Besides, the fare matrix explicitly states that.
islesv: So you have a new fare matrix?
driver: No, but the old fare matrix charges 60 pesos for Sogod to Cebu City.
islesv: But don't you have to get a new fare matrix to demand a fare hike?
driver: As I've said, the old fare matrix charges 60 pesos for Sogod to Cebu City.
islesv: OK.
driver: (thought I will hand in an additional 10 pesos)
islesv: Can I see your old fare matrix?
driver: (pressed hard on the accelerator. We were going at nearly 100 kph.)
