My first instinct always in these situations is to go to someone, a manager or somebody else with experience and ask them whatever question I have. I've worked quite a few customer service jobs and so I've gotten used to the art of telling somebody, a customer, hey I'm not really sure about this, I want to get you the right answer so I'm going to go ask my manager or my supervisor or whatever the case is. So I've grown pretty accustomed to just asking, just asking somebody. If there's nobody around then it might be a case where I just say, hey I'm going to have to put you on hold here or I'm going to have to just, you'll have to give me some time and I'll reach back to you later and give you that answer or if they need an answer right then then I'll just go with what I feel like is safe and based on the knowledge that I do have. Obviously I don't want to lead anybody in the wrong direction but yeah I just do the absolute best that I have in my ability. But yeah if there's ever someone else there who I know knows the answer I've learned to just go to them and not try to be superman and know all the answers when I don't.
