On Rotterdam in august you can help yourself with cookies, fruit, bread.
Tried to avoid the help your self food.
(caught covid anyway and wore masks all the time).
I am not a fan from help you're self.
I have seen to much selfish people in buffets around the world.
Even in covid time in a hotel, a women pick up something with her hands, removed! her face mask, put it in her mouth, licks here fingers...., mask on and pick up another thing with their hands...
So I dont trust people to pick up stuff themselves...
