<prompt> Human: My grandma wants to add me to her checking account to avoid paying a monthly maintenance fee. The idea is that because I am a preferred customer, my account fees are waived. Im pretty sure she has enough money in her account 15k that any fees she incurs should be also waived, so Ill need to go to the bank to clarify.Im immediately wary of this. Am I overreacting?  <response>: Shed be best served by finding a bank or a different product that doesnt charge her.
