"The delivery driver was incredibly unprofessional! He insisted on receiving a tip upfront. I had intended to leave a tip through the app after the delivery was finished, and I explained that to him. However, he pressed me for the amount I would tip and even attempted to take the food back if I didn't give him a tip right then and there. Because of this disrespectful behavior, I chose not to tip. To my surprise, the restaurant even called me afterward to demand a tip! Overall, it was a dreadful experience."
