Took place at Wendy's.
I pulled into the drive thru and heard "ORDER!" in a really pissed off tone on the other end. So I followed orders and gave my order. Not a major order and nothing custom. Then I hear "MOVE UP!" in the same pissed off tone. I'm tempted to speak to the manager just because I've never had a bad drive thru speaker experience at this place. When I got to the window, a manager was waiting for me, and she apologized for the person taking the order -- I guess the guy was standing behind her because there was a grumpy-looking employee in the money taking area.
I guess asshole on the window didn't have enough brains to know that management sometimes wears the headset too.
