Despite its booming service industry and its reputation as a place to have a good time, Travel + Leisure magazine last month named Las Vegas the seventh unfriendliest city in America.
Could that really be true in a city whose very existence relies upon the service industry, where politeness is one of the keys to success?
And beyond the Strip, are we all a bunch of agitated commuters angry at the world and each other?
Mark Bird is a professor of human behavior at the College of Southern Nevada. He said he wasn't surprised by Las Vegas' high ranking of unfriendliness.
"We have 40 million annual tourists to metro Las Vegas," he told KNPR's State of Nevada. "I think that cultivates anonymity and maybe curtness with strangers."
Etiquette expert Lizzie Post said many behaviors seen in a large tourist destination like Las Vegas that don't exactly meet the typical defintion of polite behavior.
"I think that a lot of the rudeness you would see would come from people just not being aware," she told KNPR's State of Nevada. "It's not big, egregious errors. It's things like people walking down the street and walking in large groups as opposed to moving over to one side. I could see locals getting really frustrated with just the sheer volume of tourists they are dealing with on a daily basis."
Part of Jean Hertzman's job is making sure employees in service-based industries know how to address issues of courtesy and politeness. She's an associate professor at and the associate dean of operations of the Harrah School of Hotel Administration at UNLV.
"It's pretty much covered in many aspects of our curriculum," she told KNPR's State of Nevada, including classes on hospitality managements, guest relations & differences in cultures.
Other popular tourist destinations were spotted on Travel + Leisure's list -- Orlando, for instance, was rated the 11th most unfriendly city.
