Avis discount as intern

Hi all. I will be an incoming intern this summer 2026. I was looking to book a rental car for a spring break trip and wanted to use the Avis intern discount, but since I’m 20, I can’t book it unless I select the “both” option(both business and leisure) use. I obviously am not on business case but is this a big deal? Something to lose my offer over? Will they check this at the rental counter?
