I went to a bakery this morning to buy a chocolate croissant for my son, ahead of me was a mum and a little boy (6ish). He was messing about a bit and taking ages saying what he wanted so she waved me in front so I didn't have to wait.
I then asked for a chocolate croissant - the last one on the shelf - and the mum said 'oh you can't have that, what if my son decides he wants it'. What would you have said/done?
