I just hand them my debit card inside and tell them what I want. Usually with an apology that I haven’t filled out a deposit/withdrawal form. Most of the time the teller will say it’s fine and the same amount of work for them either way. I’m sure it depends on the bank or branch, and I personally try to avoid the bigger banks like Bank of America or Chase just because their fees are so much higher and I hear their service is worse, so that’s probably a factor as well.
