The last time I tipped a person was in Nashville, TN. This was a couple of years ago. I was at a Starbucks at some mall. It was my first time experiencing the tip machines. I was asked to tip before even receiving my order. I asked the cashier, "what the fuck", and unfortunately I kind-of made a scene. I felt bad. I clicked 15%. They, still, ended up fucking my order. I paid the ransom, before my product was received, and they still gave me a hot drink while I was already sweating in the summer. Never again.
