damn!We have heavy construction going on RIGHT next to my bank, so a lot of workers thought it was just that. I KNEW it was an earthquake because I was on the phone with a customer who stopped mid sentence to say "We're having an earthquake, I have to go!" and hung up, and as he was saying that, I felt the shaking.
I was also pre-occupied by the bank robbery that happened half a mile from my bank, where the teller was shot.
