Not a taat but I have seen various posters mentioning 'and I've got to bake for the school fair/sale' amongst many other things they need to do.
If you LIKE baking, fine.
But most people seem to find it a chore. I have never baked for school and I don't intend that I ever will. I've never encountered a dad stressed out because he has been guilted into agreeing to bake something he doesn't really have time for.
IME the cakes are sold really cheaply anyway. If you costed the time and ingredients I'm sure its making a loss, ie it would be cheaper not to bake and just stick money in a bucket.
It just seems to be another form of everyday sexism.
