Oh, and one more if you'll hear me out: one of the things the shopkeeper can say is "Jason's discounts is coming to town." This would make sense if "Jason's Discounts" is the name of the store (singular), in which case the d in discounts should be capitalized. However, if it's referring to the general discounts (plural) provided by Jason, "is" should be replaced with are.
...except the phrase is preceded by "When fighting crime has worn you down," which isn't referring to something currently happening right now, but rather to something that will happen in the future. Therefore, it'd be more natural to say that Jason's [D/d]iscounts "will come to town," which also coincidentally avoids the is/are kerfuffle entirely.
