Tipping at a self service Kiosk

Was at the SLC airport and bought a water bottle at a self serve Kiosk. At the credit card POS it asked for a tip. I looked around. There were no workers. I had zero contact with anything alive. WTF! This kiosk company charges me 3X what a water bottle is normally bought at and they have the balls to ask for a tip? I just laughed. I’m now more certain than ever that I won’t tip unless they are getting a tipping wage. I’m not here to subsidize the owners not paying their employees nor do I want managers divvying up a tip I leave for a food server. There are many problems to our current system.
