Dear Random Guy at the Bank:
Why were you filling out your forms at the teller's window? Didn't you know that between 12:30 and 1:30 is when most people go to the bank for their bosses to make deposits? Couldn't you ask about the change of address form with a bank rep at one of those nice desks designed to assist bank customers, one of which you are clearly? Didn't you see the line of angry and impatient people standing behind you as you smiled your innocent yet annoying mid-western smile making small talk with the average looking teller?
You have no right conducting business this way in a busy city, in a busy bank.
Fill out your forms at the counter like the rest of us.
