Delicious Sushi & Steak in a Great Location

Lovely atmosphere
Atmosphere is good and so was the service. We were all a bit underwhelmed by our dishes. Presentation was good but the taste was a bit of a let down.

Each posting on AppointmentTrader shows you which user submitted it and along with that provides a trackrecord of that user which indicates how much experience

If there is no user posting that fits your schedule, you can bid on your preferred time.
Let's say Peter has a great morning and decides to take his three friends to The Bigmouth Sushi & Grill Sandton at 6 PM the same day.
He checks the restaurant's website and sees that no reservations are available. He then looks at the The Bigmouth Sushi & Grill Sandton page on AppointmentTrader, but finds that there are no user postings either.
That's where the community-driven bid process comes in.
Peter can place a bid on AppointmentTrader, which serves as a reward for any community member who chooses to work on securing the reservation. AT then notifies experienced users who may be able to help.
Step-by-Step Process
1.) Setting a Reward (Bid)
* AppointmentTrader uses historical data to recommend a reasonable reward amount for securing a reservation - let's say $100.
* Peter really wants to go, so he increases the bid (or reward) to $200.
* At this stage, the reservation does not exist yet.
2.) A Community User Picks Up the Bid
* EternalAnt36, an experienced AT user, has a strong track record of successfully securing reservations and low refund requests, they receive a notification about Peter's $200 bid.
* EternalAnt36 picks up the bid, meaning they will now work on securing the reservation.
* Peter can now talk to EternalAnt36 for any questions Peter may have as EternalAnt36 user fills the bid.
3.) Finding the Reservation
* EternalAnt36 now uses their connections at The Bigmouth Sushi & Grill Sandton to secure the table.
* If they successfully get the 6 PM table for four, Peter receives a confirmation that the reservation has been secured.
* If EternalAnt36 fails to secure the reservation, the bid is returned to the pool so another user can try.
4.) Payment & Protection
* Once the reservation is secured, EternalAnt36 receives the $200 reward which is credited to EternalAnt36's AT balance, where users manage their own funds and can withdraw via available payout options such as bank transfer, PayPal, or Zelle.
* Peter can now enjoy the dinner with his friends at The Bigmouth Sushi & Grill Sandton!
* As with all transactions on AT, disputes and no-show fees are handled through the platform's community-driven resolution system. Users with a strong track record are incentivized to fulfill bids successfully, and community members can report issues to maintain trust in the marketplace.
