we went to tesco yesterday and there is a coffee shop upstairs,whilst enjoying a coffee my 9yr ds asked if he could get some football cards and not wanting to use my debit card for 50p transaction i thought i would let him go to the cash machine,just outside the store....he is very responsible for his age and his face lit up at the thought of such responsibility etc so off he went,waved at me from the door and re appeared within 3 minutes. Anyway,dh thinks i was very irresponsable to let him do this as anyone could have got hold of him and demanded pin number etc...what do you think aibu??
