Banking

One night last week, I went to use one of my bank's ATMs. I got a warning before withdrawing that I would be charged a fee for withdrawing outside of normal hours. I refused and decided to get money the next morning. I withdrew money last weekend too and I saw on my passbook that I got charged 105 for the transaction. I can't read the language, but I'm pretty sure that's a weekend transaction fee because I'd never taken out money on a weekend before and never got that fee before. What kind of hillbilly banking system do they have here? These fees reminded me of the Washington Mutual and Southwest Airlines commercials that advertise no extra fees unlike their competitors.
