```rust
let service_address = tx_context::sender(ctx);
Balance::join(&mut fee1, fee2);
balance::join(&mut fee1, fee2);
transfer::transfer(coin::from_balance(fee1, ctx), service_address);
```

`fee2` is merged into `fee1`, turned into a `Coin` and sent to the `service_address`. Finally, we signal Sui that we have deleted both wrapper objects:

```rust
id::delete(id1);
id::delete(id2);
object::delete(id1);
object::delete(id2);
```

At the end of this call, the two objects have been swapped (sent to the opposite owner) and the service provider takes the service fee.
