I'm going to complain about having to pay an extra $2 for a ride at the pier for my son
Why would you complain, did you expect your son will be free?
I didn't have to pay extra for me, but my kid is really angry.
It is annoying to have to pay extra but it is normal that different groups of people have to pay different fees. It is not good to be stingy, people will think you are cheap.
If people don't like paying extra then they should just not use the service. I pay extra for other stuff all the time.
I agree, so do you not think your reaction is a little bit unnecessary? If you pay extra all the time then you should also expect that the ferry may have charges for children now and you have to pay extra for them.
