I do not want to value medical care, which until now has been good, but the cafeteria service. As a companion of a person admitted I had a very unpleasant experience yesterday, October 2, at the time of dinner. I went down to get a sandwich and a bottle of water for dinner (because despite being in the dinner schedule there was no other option) and paying 20 euros, gave me the laps as if I had paid with ten. I warned him and, in very bad ways, he told me he was lying and that he was going to give me the ten euros that were missing, but that he was going to record the time and check the cameras. I told him to go ahead, without any problem. It seems shameful to have to endure this deal and try to steal in such a blatant way.
