My favorite story for this type of stuff was in college when the bank double cashed a check I had written. I went below 0 (it was my rent) and 5 other checks (for less than $50) bounced. Cue $175 in overdraft fees.

I went in to fix it and they realized they double cashed my rent (still not sure wtf that was about), and they added back on the amount of the rent. It took another 2 weeks to get the fees removed. I had to call and visit 8 times. Being $175 down in 1988 was not fun.

I switched banks, but as a student I am pretty sure these days I would have used something from Walmart or another group. I bank with a credit union now and they are amazing.
