At the end of the day we all know the score.
Simple case of "OOPS"
I have experienced quite a few "OOPS" moments and I am sure a lot of other people have too. Not nice when it happens but stuff happens.........
What would I have done?
What I have done a few times in the past, go downstairs to the bar, have another (possibly soft) drink.
At least it hapened in a hotel where there is somewhere to wait. Beats waiting in the cold in the car or wandering aimlessly some distance from the appartment because you don't want to look suspicious.
