My son started guitar lessons at school last year. We didn't check the cost until after we'd agreed to take the place, it turned out it was £17 for half-an-hour.
We've just received the bill for this term which says £17.50 for half-an-hour.
No explanation, just a bill. 50p is not that much, but the prices are already high and he should have asked us.
Is he taking the piss, or what?
