The first time I saw a tablet asking for a tip, I automatically gave one. Afterwards I thought about it and realized that was stupid. I've always declined the tips ever since. Nobody has batted an eye at my declining to tip and half the time the person at the register just says, "It's going to ask you for a tip, just decline it." Even they know it is stupid. But, it had the side effect of making me mad about tipping. I had increased my tips to 20% over the years, but now I've gone back to the old 15%.
