DON'T DO IT.
I did it for awhile way back when I was younger and dumber and it's a nightmare job. It's not glamorous. Your customers are 99.9% "dick-suckers" (as my coworkers called them). In other words they're all brothel workers who just go to the host club after their shifts end since most are too messed up to relate with guys outside of their industry. Oh, and they come in AFTER their shift ends so most host clubs don't even start until early morning. Some open at night around 7PM, but most OPEN at 4-5AM. Your sleep cycle will be destroyed, your liver will be annihilated, and your coworkers and clientele will both be in poor mental shape as well.
Yes, there are exceptions. Yes, there are successful hosts and sometimes real women visit, but both are unicorns.
Again, DON'T DO IT.
