The staff tried to charge me a one-way rental fee, but I showed my rental confirmation voucher (page 2: Oneway rental fee: included), and that resolved the issue. I believe this shouldn't have happened in the first place. All the charges paid should be detailed in the rental company's system, and renters shouldn't need to provide proof of payment. What if I hadn't printed the complete rental confirmation voucher and couldn't provide the second page? Would I have had to pay the one-way rental fee again?
