I don't think it's fair.
What is fair, is requiring a make-up fee because a student slept in, was hung over, or had something else to do that day. In those cases, I used to bill $100 for my time, + gear costs, and outlined this in the student agreement, plus read it out loud at the beginning of class. As an instructor, it cost me money for no-shows.
But the instructor knew the day before that you were'nt going to dive, therefore the staff should not have billed for your remaining dives. There is no "rental fee" - that's a profit center, and costs the store nothing to give you for free. The $25 instructor fee - the first instructor should never have billed for your remaining dives in the first place, so that's bunk. General practice in my neck of the woods is to be as accomodating as possible, and it sure doesn't sound like they were caring about your ear problems (which were likely caused by diving).
It's a good policy, but not in your situation. Speak with the owner. Worst case scenario, it does sound like you suffered an ear injury from your earlier dives, so you can always bring that up to the owner, in which case I'm sure you will get more than attentive service thereafter.
I hate poor customer service, but perhaps the person you were dealing with just did not have the experience to tell what the policy was designed for.
