POMPANO BEACH, Fla. -- A customer in a South Florida drive-through paid the bill for the customer behind him on Thursday, and the chain continued throughout the day.

Drivers at a Starbucks Coffee in Pompano Beach paid for drinks for the people behind them all day long.

"Your drink has been paid for by the driver in front of you," a Starbucks barista told a customer.

The barista said she had one woman convinced that they were on the TV show "Candid Camera."

It all started with one customer's gesture of paying it forward.

"I think it's awesome," one customer said. "Spreads a lot of Christmas cheer."

The manager at the Starbucks said the idea has made his work atmosphere cheerful all day.

"Every customer that comes through the drive-through has been smiling and saying, 'You made my day.'"

However, the chain of kindness started with anger. Arthur Rosenfeld said the man behind him at the drive-through on Thursday morning was honking and yelling at him. So Rosenfeld, a Tai-Chi master, responded with a bit of Zen.

"It wasn't an idea to pay anything forward, nor was it even a random act of kindness, it was a change of consciousness (to) take this negative and change it into something positive," he said.
