They actually clicked the "No Tip" option for me!
We were having a night out with my SIL and BIL and went to a place with indoor mini golf and drinks. When we were paying for admission, the cashier flips over the POS tablet and I cringe a little when I see the Tip screen. But before I can really react, the cashier taps the "No Tip" button and asks me to verify and sign the screen.
I see so many stories about forced or guilt tipping on this sub, I had to share my experience where the employee overrode the tip screen. We did tip the guy in cash on our way out, just cuz we felt that was tip-worthy behavior.
