True story, I was in a line at a grocery store when an old woman ahead of me told me I looked like her dead son

She started crying and touched me saying you look just like him, the hair, the eyes, the smile. I just stood there awkwardly trying to hold it together. Before leaving she asked me for a strange favor - When I leave, could you just wave to me and say “Don’t worry Mom!” It would just mean the world to me, I miss him so much and he always would tell me that when he was alive. Reluctantly, I give in and agree to her request. After what seems like an eternity, I reach the cashier and she rings me out. The total will be $150 she says. Confused, I tell her that must be a mistake, I was only buying a candy bar and a soda, the total should be less than $10. The cashier says that’s right but your mom just told me that your covering her purchases. All of a sudden, my confusion turns into anger after realizing what happened. I burst out of the store and see the lady trying to climb into her car. I grab her by the leg and starting pulling it - just like I’m pulling yours.
