Ive never met Harry at the club Im at...but he used to go in The Hard Rock Cafe when I worked there. Very rude and full of himself...and the waitresses always complained that the managers would comp his meal and he would never leave more than $5 as a tip on a party of like 6 or 8 folks usually. My wife has waited on him at the casino and says the same thing.
Alot of young celebs come into my club...Ive met alot of the music artists that ae popular for the week...I met Kid Rock a couple of months ago (very real guy bought me alot of shots), Nicholas Cage, Melissa Gilbert, Jud Nelson, Laurence Fishburn, Vince Neil, Patricia Arquette, Dennis Rodman, lotsa football players that I dont know, tons of has been rockers,a few gonna be rockers....as far as how do they tip....it varies, those that like to show off do it big just for the sake of showing off....most are very low key and dont flash it like you think they would but are fair and wont make you think they are cheap and disrespectful...some wont give up a dime and treat the girls like garbage. The popular thing for rap artists right now is to "make it rain" which is going to the second floor and dropping $100 dollar stacks of singles on the dancers on stage...thats always fun for the security guys!!
