Charlie Sheen is taking sides in the “Tip War” involving NFL star Lesean McCoy — claiming he’s giving $1,000 to the waiter McCoy stiffed after a controversial lunch earlier this week. Actually, it wasn’t a technical “stiffing” — the Philadelphia Eagles running back tipped a waiter named Rob 20 cents on a $61.56 meal at PYT restaurant in Philly. The receipt — with the 20 cent tip — was later posted on social media by the owner of the restaurant, Tommy Up.
