The sentence from the paragraph that has the misplaced modifier is the following: "The salesperson handed a receipt that was very long to each customer". A misplaced modifier is a word, phrase or clause that is improperly separated from the word that it modifies. In the paragraph presented in the question, the last sentence presents a misplaced modifier as the phrase "that was very long" is not placed properly, making the sentence confusing. Is the phrase modifying the receipt or is is talking about the customers?. In order to be fixed the sentence should go" The salesperson handed a very long receipt to each customer.
