Chick-fil-A restaurants strictly enforce their employees to uphold 100% customer service, with positive attitude.
On our visit, it was very clear the cashier HATED his job. When asking for refill he would sigh or when taking our (and the people in front of us) orders, he would look to the floor or out the window as if he cannot wait till his shift was over...
To perfectly describe the cashier, would be the "Dry Eye Guy."
Not to mention food was cold and the cashier made everything feel worse/uncomfortable.
