So I was just at the bank and while I was at the customer service counter a older (60ish) woman came up and stood at the counter too.  I had to bite my tongue but I wanted to ask her if she could move back because I was handling private business and she didn't need to stand there and listen in.  I did not say anything but would I have been wrong to please ask her to step back so I could conduct my business a bit more privately?

Edit: there was only one rep at the counter.
Yes!
A coworker got so close to me at work once. He was towering over me while I was sitting behind my desk in my chair. I said, "Listen, if I can stretch my arm out & touch you...you are TOO CLOSE." The same guy once tried to squeeze past me while I was standing in a doorway 7 months pregnant. I said, "Dude, I cannot suck my stomach in any more than this. Just say excuse me & I'll move."
What the heck?!
