This is why you should always be kind while waiting in line.

One Australian woman claims to have pranked a fellow McDonald’s customer who acted rudely while waiting to place a drive-thru order – by paying for the driver’s meal, and taking it herself.

In a now-viral screenshot that hit Twitter on Sunday, Facebook user Kristy Morton spilled the story in a Canberra-area group, News.com.au reports. The post and its unbelievable “plot twist” have since gone viral with over 4,500 likes and 700 shares, the Twitter sharer said.

MAN IN HORSE-DRAWN CARRIAGE KICKED OUT OF KFC DRIVE-THRU

“I was in a long McDonald’s drive-thru this morning and the young lady behind me honked her horn because I was taking too long to place my order,” Morton began. “I thought to myself 'Take the high road.' So when I paid for my food at the first window, I paid for both our orders.”

“The lad at the counter must have told her what I’d done as she leaned out the window, waved and mouthed ‘thank you’, obviously embarrassed I had repaid her rudeness with kindness,” she continued.

“So when I got to the second window I showed both receipts and took her food too. Now she has to go back to the end of the queue and start again.”
