The Hair Cut

I went to the barber yesterday for a hair cut and I had to pay 25 bucks for the same. I was wondering, I have less hair and why should I pay regular charges. But then I realised that the cost is not just to chop the hair a bit but also to chop it in such a way that it souuld appear as if I've had a haircut and at the same time make it look like I've not lost any hair. I must admit that the barber did a pretty good job and I ain't complaining anymore.
