The directions were clear: Bring one pizza to the Sheraton Hotel in Ann Arbor at precisely 2:20 p.m.

That's all Pizza House manager Brian LeFevre knew about an order placed Thursday morning. When it came time to deliver the pizza, he sent the next man in line out to the hotel with the single pizza.

When the driver returned, it was impossible not to notice how giddy he was.

"He wanted to keep it to himself, but you could tell he was happy about something," LeFevre said. "He said it was 'a life-changing delivery.' "

The driver - who declined to comment for this story - was given a $2,084 tip from a room full of real estate agents from Keller Williams Realty who were gathered for a conference at the hotel.

"I think everybody in the room was in on it except for our driver," LeFevre said. "I was managing at the time and I heard about the phone call but there was no indication it was going to be anything but a normal delivery."

LeFevre said the driver has worked at the restaurant for a few years.

A video of the exchange shows the driver entered the room and was given a few winning lottery tickets, a Visa gift card and some letters of encouragement from the people in the room who wanted to express appreciation for the work delivery drivers do.

"We recognize that people go through the world all the time wondering if anyone notices them or does anyone appreciate them," the emcee said to the driver. "We notice you and we appreciate you. Thank you so much."

After being presented those gifts the driver was handed a cup full of cash that totaled $2,084. A video of the events shows the driver's disbelief over the tip.

"All I did was deliver pizza," the driver says in the video.

LeFevre said he hasn't seen a tip of that size for a driver or in the dining room while he's worked at the restaurant.

Last month, an Ypsilanti man raised money during an online gaming session that resulted in a $1,200 tip for a Jet's Pizza driver. In December 2013, "Tips for Jesus" resulted in $10,000 in total tips being left at a few Ann Arbor restaurants.
