Something Sinister In The Kitchen

My mother and my aunt and uncle and I once went to a lovely looking restaurant while holidaying in Portugal. It was scalding hot so we ate in the enclosed area outside. A window was open that apparently was part of the kitchen. But no sooner had we sat down and ordered our food than we heard a terrible retching noise coming from the kitchen. We all stopped and the retching continued. It sounded like someone was throwing up or coughing really bad but in a monstrous tone. It was really loud and quite disgusting as we tried to eat our meals. The retching seemed to be turning to roaring as if some strange demonic creature was in there. We looked down at our half eaten food and were suddenly wary about eating it. But so as not to insult the waiting staff, we ate it all and left with the thing still roaring and retching in the kitchen.
