On some Gigs, a Sender will add a tip upfront. Those Gigs will have a "Tip Included" tag. Senders typically use this as an incentive for going above and beyond for things like urgency and heavy lifting. You can see those reasons in the Gig details, along with the amount added and the original payout for the Gig.
You’ll see the “Tip Possible” tag when customers have the opportunity to tip after their items have been delivered, like on Walmart deliveries. When tips are added after-the-fact, we’ll send you a notification with the amount that’s been added to your payout, and you’ll be able to see it itemized within your Gig History in the Driver Dashboard.
