Elis - Unlucky driver

Elis is visiting her friend in Prague but the trip is long and she really regrets not having used the toilet before she left her flat. The D1 highway is being reconstructed and the last gas station was out of order. Elis starts wondering whether there will be any more gas stations before she arrives in Prague. She knows there's one right at the highway not far from her but it may be too late before she gets there...
