Purpose of tipping staff at a "juice bar" club?

I always tip the bouncer running the CR. Gives me extra time to finish and one time I was so shitfaced I lost my phone and didn't even know it until one of the bouncers said I found your phone outside. The prior time I had dropped about $400 on the floor he found and returned. Did not accept a tip for either act and just said "no need, that's what friends are for". As much as this will sound pathetic I will say it anyway: I tip everyone great, everywhere I go because I am blessed with a great life and feel a moral obligation to do so. Tipping tip: Tip the valet when they take your car (I tip on both ends) as well as housekeeping.

its similar to when people dine in at fast food dinners and pay more for large drinks. why dont they get the small drink and get refills because theyre free. i dont understand

If you tip them, they may do the douggy

If you are able to do what you want/like in the club w/o anyone telling you o/w, then no need to tip - some clubs run a tighter ship and tipping staff may help w/ them looking the other way.
