present mindee's mum is always at least 5 mins late dropping off, shes aware i have to leave at certain time for dd's school run, but doesnt make difference..now, she's started turning up later to collect her..diff reasons, but one day was 20 mins(no phone call) another was 45 mins(phone call after already 20mins late)...dp thinks i should let it pass, but now i am actually able to charge, i think i should be adding the lateness collecting onto her fee..what do you th ink think??? and what would you say to parent?
