<prompt> Human: I got an offer in the mail to effectively earn 3.3 of an investment after 6 months. open an account with 15,000, get 500 after 6 months. Is it common practice for people to bounce between banks, and if so, is there any reason my current bank would be interested in matching beating this? Is this something I could do such as going to my current bank and get them to try to retain me as a customer? Or, is it just worth taking the offer as it stands.  <response>: No. Be disloyal. Loyalty does not pay in banking.
