Why Trump was seen with a wad of cash

"I don’t carry a wallet," President Trump told reporters Wednesday after being caught with a wad of "Andrew Jacksons" peeking out of his back pocket while boarding Air Force One.

The $20 bills slipped into the view of eagle-eyed photographer, Tom Brenner, at Moffett Federal Airfield in Mountain View, California, on Tuesday, according to Yahoo. The snapshot went viral.

When the president returned to Washington, curious reporters asked if it was normal for him to carry cash.

“I don’t carry a wallet because I haven’t had to use a credit card in a long time," Trump told reporters while pulling a wad of cash from his pocket, according to Yahoo. "I like to carry a little something. I like to give tips to the hotel."

The move sparked questions about how widespread the practice is amongst some high-profile industry leaders and former presidents.

Back in 2013, former President Barack Obama made a pit stop at Magnolia’s – a deli and café in Rochester, New York. Obama’s bill added up to $89.64. Though the restaurant already added an automatic gratuity of 20 percent, Obama didn’t think that was enough, according to TMZ, who obtained a copy of his receipt. He tipped an extra $30 on top of the $16.64.

Hilton’s president and CEO, Christopher Nassetta, told New York Times columnist and CNBC co-anchor Andrew Ross Sorkin that he does not tip housekeeping when he checks out of hotels, according to Business Insider.

"I typically do not leave a tip," Nassetta said at the 41st Annual NYU International Hospitality Industry Investment Conference, where he spoke to thousands of hospitality-industry professionals on how he had worked his way from "about as low as you can go."

A Hilton spokesperson confirmed with FOX Business that Nassetta issued a clarification following his comments at the conference. The clarification is as follows:

“When it comes to tipping in hotels, I have always had a different approach to work and personal travel. I also never meant for my approach to work stays at Hilton properties to discourage others from tipping when they are traveling. Going forward, I will tip when traveling for both work and personal travel.Nothing is more important to me than Hilton’s culture and team members, especially our housekeepers, who are central to delivering Hilton hospitality around the world. I have always been generous with my time and engagement with team members when on property, and I will remain focused on keeping Hilton the #1 best place to work in the United States.”

Carrying cash is foreign to many consumers as mobile-payment services such as Venmo have gained in popularity. A 2017 survey from U.S. Bank , found 47% of respondents preferred digital apps when making payments. Forty-five percent of those surveyed preferred cash.

The survey also found that fifty percent of respondents carry cash less than half of the time. If they do, according to the survey, they keep less than $20 on hand.
