Jules made one of the more common "young gun guy" errors. Maybe, as he gets older, he'll get smarter.
When you see the shooter has gun A, but has ammo B that does not work in gun A, the correct thing to do (actually, the CORRECT
thing to do is to keep your damn mouth shut, unless it is dangerous, because it is none of your business), I say the correct thing to do is ask, "Why'd you bring the shorts?" That way Beth would say, "I brought 'em to shoot in this Astra", and Jules would say, "Ah", and still look intelligent (which is very important for guys, especially around girls).
While the "dumb young gun guy" error is to say, "You brought the wrong ammo, you dumb idiot", whereupon the shooter produces another gun and says, "No I didn't. I brought it to shoot in THIS, you dumber idioter."
