Would I make a bad fit for a cashier?

I need a job, and my local goodwill is hiring. Im terrible at counting money. Just today I was looking at change and forgot the value of a nickel and a quarter. I had to Google it, even then I had trouble counting it. Im okay Imteracting with people briefly, but I don't know if I could do it all day, especially if a customer gets upset with me, I don't know how I'd deal with it. I'd probably have a panic attack.
