# Remove a line from the Berlin City Tour basket

Automatically remove a line from the Berlin City Tour basket on berlin-city-tour.de. Takes one line out of a Berlin City Tour basket, using the cartId and cartPackageGroupId that add_to_cart returned, and reports what the basket holds afterwards. This is the counterpart to add_to_cart: because the shop merges repeated adds for one travel date into a single line, a run that was retried leaves more guests on that date than intended, and this is how that is undone. It refuses when the basket has no such line, and it checks the line is really gone before reporting success rather than trusting the request it sent.
