Are you annoyed by really picky eaters?

I don't mean people who simply prefer one thing over another, instead I'm referring to those people who are so particular in their food likes to the point that they are annoying. You know who I'm talking about.... when you make a fast food run for everyone, it's the guy who gives you 50 million instructions on how he wants his meal prepared, or it's the person who you're stuck behind for 10 minutes in the drive through because it takes that long for Taco Bell to get his burrito just right. Maybe it's your coworker who won't shut up about exactly how she likes her chicken alfredo served. How do you feel about really picky eaters?
