Geniuses who work at banks

Earlier today, I went through the bank drive through to make a deposit for my mother. Employees of this bank have said many rude and inexplicable things in the past. This is today's installment.

Teller: Welcome to blah blah blah bank. How are you today?

Me: I'm fine thank you. I have a deposit, but my mother forgot to write the account number on the deposit slip. Its supposed to go in the account that ends in 1234. (not the real last four digits)

Teller: We don't give out account information.

Me: Well then aren't we lucky I didn't ask you for any. The deposit needs to go in the account ending in 1234.

Long silence.

Me: Hello?

Teller: We'll do it this time. What were those last four digits?

Me: 1234.

Teller: Thank you for banking with us and have a great day!

Me: Oy.
