Customers Are Sooo Freaking Dumb.....

My boyfriend has just introduced me to a really really funny website Not Always Right.com  This is some of the funniest dialog I have ever read.
Below is an excerpt from the page that I found very funny but I also wonder are these people serious.I mean no one can be this dumb.

When Funding Is Poultry
Fast Food | Miami, FL, USA

Customer: “Hi, can I have the chicken salad without chicken?”

Me: “Uh, you mean a regular salad?”

Customer: “No. I want the chicken salad without the chicken.”

Me: “Ma’am, a chicken salad without the chicken is just a salad.”

Customer: *stares blankly* “What’s the difference?”

Me: “There’s no chicken.”

*customer stares blankly*

Me: “It’s cheaper?”

Customer: “Okay! I’ll have that!”
