Tour operators collect people from hotels and take them to the airport. They take 1-1.5 hours, and 15 minutes before the entrance to the airport itself they stop at a "sanitary stop". Who needs her here when there's nothing left to the airport??! In fact, this is the last attempt to rip off tourists at exorbitant prices (there will still be small shops of Turkish products in dutik).
The only advantage of this stop is to admire the tradition of baggers to tie bracelets from hotels on bushes.
