Lately, this year mostly, other people ordering fast food or Dutch Bros. drinks, they've been offering to buy my food or drink. I let someone buy my Subway sandwich, a middle aged man. I shook his hand and said Thank You. Another time, I went to Dutch Bros. and was in line after some guy. He turned around and offered to buy my drink. I said No Thank You. When I go to get drinks at fast food restaurants, crew members I don't know up-size my drink and charge me for a value size or small. Idk why? Are people always this nice when it comes to fast food?
