Only Tip on $138 Meal: 'Single Mom, Sorry' Incident, real or not, sparks a firestorm on Reddit By Liam Carnahan, Newser Staff Posted Nov 2, 2012 12:15 PM CDT Updated Nov 4, 2012 7:00 PM CST 67 comments Comments "Single mother, sorry" (shutterstock) (Newser) – Here's a tip for bad tippers: Don't make lame excuses. That's a lesson one woman may be learning after allegedly leaving no tip on a $138 bill at a restaurant, and instead writing on the bill, "Sorry, single mom." As if that weren't bad enough, she scrawled, "Thank you it was great" at the bottom, reports the Huffington Post. A photo of the bill first went up on Reddit, and the story has gone viral since. Commenters have weighed in on the usual pros and cons of tipping, and plenty of them think the bill might be a fake. Another camp thinks that the lack of a tip is real, but that the person who left it isn't a single mom. Whatever the truth, it all "points to a larger issue," writes Mari-Jane Williams at the Washington Post's On Parenting blog. "Increasingly, it seems, single moms are being used as the butt of jokes or, even worse, a scapegoat for societal ills."
