I'm a cm and one of my parents is always late to collect. I have fined her, complained, explained impact on me, my family, other kids. It makes no difference, she apologises but is then at least 10 mins often 40 mins late.
I was going out tonight so waited 10 mins, didn't show so I left and took her child with me. I texted address and said to meet me there, the place is hard to find and she got lost, she wasn't pleased said why can't you just fine me.
I know I can fine her but it's not effective, and I don't want the extra money I want to leave work on time! A friend has said she would be furious if she went to her children's nursery and they weren't there even if she was late. I ended up delaying her an hour tonight when she was only 10 mins late, however I still feel it's fair enough really, am I wrong.
