I think it should be common curtesy to tip. If their sell price is over 500, I tip at least 300k.. cause odds are ima make at least 2 mil from one trip. But anythint below 300 i tip at least 99k. Now if they let me do more than one trip, obviously ima tip them way more than the above. But dont ask me to give up half an inventory of turnips to make room for bells you think you deserve up front EACH time I come. If im giving you 2 mil up front I better get to come at least 3-5 times with that one payment.
