The speaker at a bank's drive-through window had been broken for weeks, and the tellers had to resort to miming or writing notes to communicate with their frustrated customers.

One day a sweet elderly lady who came to the drive-in every week pulled up to the window, leaned out, and smacked the glass in front of the teller's face.

"I hope this is bulletproof," she yelled.

There had just been a robbery at another bank nearby, so the teller was touched by her concern.

"It is," the teller yelled back.

"Good," she continued, "because someone is going to shoot you if you don't get that blasted speaker fixed!"
