The generous diner has also been stamping bills with @tipsforjesus – a Twitter handle for an account that has 3,500 followers, but, oddly enough, no tweets.

The tips, which stretch from coast to coast across the US and have also been left in Mexico, accompany an illegible signature on the receipt and occasionally the handwritten message ‘God Bless’ is also added. The last time a tip was left was on Sunday, when staff at the Seagrape in Connecticut found out that thay’d been given an extra $5,000 for their trouble.

The shy tipper has an Instagram account with over 56,000 followers, and every time he tips, he takes a picture of smiling staff gleefully holding the receipt.

If you’re out there, mystery tipper, we’d love an exclusive – feel free to get in touch!
