Programmer Humor

That goes back to the point I was making earlier. For some reason a bank teller is hired for the same wage for the same hours, but I can almost guarantee you that because of the ATM they spend significantly less of their work day "working" because the ATM was designed to do a significant portion of their job. There certainly is an excuse to keep them around all day, there are some unavoidable tasks that only a human can do and they come up at random times throughout the day, but the ATM has replaced many of the working hours the bank tellers used to have even if the job didn't go away.
