No, Potluck Trip is not a paid tour or exchange service. A local should never ask a to pay for their service, and the traveler should never offer money. We do recommend that a traveler to show their appreciation by bringing some local souvenirs or delicacy or offering some other gesture. Locals should only offer what they are able to offer freely, and say what those things are clearly when you are contacting each other. If there are some things that can’t be offered unless the traveler agree to share the cost like eating a meal or coffee, this should be discussed between the locals and traveler.
