We were in the bank today and my ds offered a crisp to the baby behind us. I told him that he might not be allowed it thinking he was too young and he should ask his mummy. I then looked down and saw this baby (under 1) was holding a mcdonalds wrapper. I assumed that it was just for him to play with but then the mum said to ds "oh he's probably full up he's just had mcdonalds" 
I think she saw the look on my face when she said that as she gave me a very funny look!
Please tell me I anbu and that it's not just me being odd about it!
