That’s the way it goes. I have people all the time who tip me who really don’t have the money. It’s all about a persons class. Some people feel rich with life but money. 
the wealthy don’t tip and always lie about it. Any wealthy pax that say they will tip me on the app get an automatic 1-star rating from me.
EVERY wealthy pax that said they will tip on app never has. Tippers tip, non tippers say they will tip and this is a fact. I rate appropriately. I’m guessing you are new at this game, huh?
I get tips all the time from people that say they’re going to. Them tipping or not really shouldn’t be how you rate. Especially that low. What if they one star you for not having water or candy? Or for showing up 3 minutes later than the projected time? Would you find those ratings accurate and justified?
