On the Sunday episode of No Agenda the Tip of the Day was that precalculated tips at business kiosks and receipts are miscalculated. Time finding this to be true!
I just ordered pizza, total was $18.51, they said 15% tip is $3.15. My calculation and Google said it should be $2.78. Bastards. I always carry out to avoid the tip.🦝
