Fair enough for the bus stop, they're for buses. Maybe Dunnes or someone else reported you as an obstruction on the other occasion. I'm not sure what the drivers' relationship with the Gardai is like up above in Dublin city but a local Garda wouldn't do you in Swords unless you took the piss. Traffic Corp just ask you to move, you'd have to tell them to fuck off to get a ticket. Anywaysanall, €40 isn't the end of the world.
