In a busy coffee shop with 8-month-old DS and our NCT group. A woman pulled an extra chair up to join her friends at crowded table next to us. She sat down within grabbing range of DS and before I could stop him he twisted round in highchair and grabbed hold of her pale grey coatigan thing that she'd draped over chair and wiped his mouth on it
He had prune puree and yogurt around his mouth as I was feeding him 
Woman jumped up angrily and told me off. I apologised profusely but she was really angry. She insisted I pay for dry-cleaning. I refused (had she been nicer I may have offered) but she was making a scene and I loathed her.
If you sit within grabbing distance of a prune-covered baby surely that's not my fault? Or am I BU?
