I love this movie, except for one thing

Rating: 8/10 (5 August 2017)

This one problem isn't enough to bring my rating down from an 8 to 7 because it's not a big deal, I'm just saying: it occurred to me that Jerry just stopped by his father-in-law's office building to try to finalize the deal. So, how would his windshield be so iced over when he comes out? He doesn't work there--he works at the DEALERSHIP--so it's not like he was there all day with his car out in the lot for hours.
