A couple was greeted with quite the surprise when getting breakfast at a McDonald's in Hermitage, Tenn. television station Newschannel 5 reported Tuesday.

Greg and Stacye Terry, who are regulars at the McDonald's location were accidentally given a sack containing thousands of dollars cash.

"My husband opened the bag and discovered the money inside," Stacye Terry told Newschannel 5. "He said, you are not going to believe this. Sure enough, it was their bank deposit money."

The money was somehow put near the franchise burger chain's drive-thru window, and placed in the Terry's hands rather than their breakfast food.

"The second that he said it was their deposit, my first thing was let's get in the truck and take it back," said Stacye Terry. "There is no other way to have it. I couldn't live with myself.

The McDonald's employee who had given the couple the cash, was at their residence in a jiffy before the two could physically return the money.

"We are grateful for this customer and the action they took upon realizing our error," Phil Gray, owner of the McDonald's location said in a statement. "We are looking into why this mistake happened, but what is most important to us is knowing that we are part of a community with the values that were evidenced by this person's actions."

The mishap is not going to deter the couple from their daily routine.

"We'll be back. We'll be back," Greg Terry told Newschannel 5. "But, next time I'm sure we'll leave with our normal breakfast order."

McDonald's customers will see a third drive-thru pickup window at all of the company's restaurant locations next year in efforts to speed up the time drivers spend in line.

A study from QSR Magazine indicates customers currently go through McDonald's drive thru lines in 189 seconds, a decrease from last year. This is 31 seconds slower than Taco Bell at 158 seconds. Wendy's comes in third at 134 seconds.
