A couple days ago I needed to withdraw more cash from my bank account than you're allowed to via the ATM so I went inside the bank--something I hadn't done in a while.
The teller looked at my withdrawal slip and said "THAT's your account number?!" I didn't know what she was talking about, but she called two other bank employees over to look. One looked at my withdrawal slip, then looked up at me and said, "WHEN did you GET this account?!"
Apparently they don't see account numbers like mine anymore. Not sure what they meant by that--it's not like my account number is 000000001.
