Well here's my hypothetical. Every single car agency issues contracts that are 283,838,443 pages long in an 8 font. Every single contract varies slightly. Are you going to read through all of that on the off chance that on page 182,828 there is a clause in your contract that says you actually have to pay 10 times the amount shown on your orignal reservation and on the first page of the contract?
That's pretty much the way many people feel about reading through pages and pages of tiny letters of usually standard boilerplate language
