Stolen from table on way to dessert in buffet restaurant!

To fortify myself after shopping, the restaurant: "El Buffet Lliure" suited me just fine. After being shown to my seat, I was brought cutlery (knife and fork) and a glass to the table by an unhelpful employee. I could overlook the disturbing music, but the choice of one size of plate and the cutlery of only large forks, knives and spoons was then very disturbing.Low food quality would be putting it kindly! It is clear to see that the emphasis is on "mass and not class"! But in the last few minutes of my visit, we came to the main experience of the restaurant visit, which was actually designed for relaxation. As I went to eat just before closing time, the staff started eating next to my table (which I don't find disturbing at all). After fetching dessert, a maximum of two minutes, I found neither cutlery nor my purchases at my table! I immediately informed the next condition. He ran off through the area and seemed to make an effort to find the shopping. But the search was unsuccessful. I was led out of the restaurant, which was only filled with employees, and told "I have to carry my shopping with me and it's my own fault". So I had to leave the restaurant empty-handed. The service staff told me that thefts were not uncommon in their restaurant and told me about recent experiences. As I was unfamiliar with this 'default' and was assured "there is nothing we can do", I would not like to give a recommendation!
