I don't do this anymore after I got played.
Was approached by a chick at a Jewel Osco who said she was trying to get some stuff for her kids that she couldn't get on the card, and offered to do a swap. Said kids where right next to her btw, so I'm thinking its legit. Around 10 mins later I happen to see her in another aisle filling up her grocery cart with liquor, and let her kids get only 1 of those little snack potato chip bags each.
One of the lil homies asked if he could get one more since he was hungry and she told him to shut his fukking mouth. Ain't my kids but I was 5 seconds away from going off on her ass, but realized it ain't my business.
So I'm not gonna support shyt like this no more cause I don't trust people's intentions when you trying to help them out.
