How do you write this sentence correctly?
This quote sentence appears in my essay:
The narrator describes, “Chuck imagines having a cell phone, texting Margo while she is at home or at the KwikMart. ‘Out of BBQ today, Shipment in tmrw. Burned finger on pan!’” (Blevins 159).
Where this is kind of a quote within a quote, I'm unsure if I'm punctuating it correctly. How do I write this? Should the exclamation mark be placed at the very end instead? I'm so unsure.
