Thank you, Steve. This is very helpful. I think I'll be banking with them as they were very kind. I just needed to check some things out first and make sure this was legit. As systems are different here than what I'm used to I just didn't want to rush into anything that wasn't above board without doing a bit more research. I admit I was a bit overwhelmed so said I'd be back next week. Your answer makes clear what I was wondering about. They may have been offering a credit card account rather than simple savings. I wasn't sure I was able to get that as a temporary resident on a rentista visa, so assumed it was for basic savings account and felt a bit uneasy. While I wasn't needing a credit card, it could be useful to build credit. Will go back with a bit of clarity and my wits about me and speak to the teller again.
