I must admit, it was a big culture shock moving to Dublin and trying to get used of the buses.I don't think I was one of those people who tried to hand the bus driver a fiver but I definitely threw in €4 and waited for my change along with my receipt. Not happening. Hopping on the bus means either one of two things, you better have the exact change ready or pray that there's money on your leap card.But, you don't have this problem down in Cork. Only have a €50 note on you? No problem.Want your change back in all €1 coins? Sound as a bell.
