spelling out words that appear foreign or unusual

Many of the posts on this site show instances where country folk mispronounce words in funny ways. However, there are times when they encounter a long/foreign/unusual word that is so daunting for their country twang that they don't even attempt to pronounce it. Instead, they concede defeat and simply spell the word.

Example:

Cashier: Welcome to Wendy's. What can I get for you?
Customer: Yeah, I think I'll try that combo number 8 - that A-S-I-A-G-O ranch chicken sandwich, howevah you say it.
