So you want to get a job working in a club in Las Vegas. This is a tough job and it's going to take a lot of effort, of which I cannot mention on this website, of what it takes to get the job. Well I'm kidding a bit on that, well sorta, not really but you know what I mean.
Working as a host in a night club is a bit intense. You have to deal with a lot of drunk people and a lot of people on drugs too. Las Vegas doesn't always bring out the best in people. Sure you see celebrities but unfortunately you are treated like a 2nd class citizen by most of these people. Even if they are mega rich don't expect any tip from them.
Any time you apply for one of these jobs you have to look your absolute best, like you're going to the club. Make friends with the bouncers and go to the club, give the manager or owner a reason why you like the place and want to work there.
