When you let someone over to sell turnips in your town, people start to expect tips. I always thought of tips being as something you felt like you should give, not a requirement. I always give 10% of what I make, but I do it out of the thankfulness of my heart. Earlier in the train station, I saw someone force you to pay 700k to come to their town to sell. It's your town, you can do what you want, but it doesn't seem like a tip. It's more like you have to buy.
