in many Spanish tapa bars (beer bars) we find ham hanging on the ceiling to dry of. The little red/white hoods underneath collect the oil which is running out. In spain people like to go out for a beer or wine and eat a little snack, called tapa. In former times tapa was the lid that was put on top of a glass to prevent flies or dirt to fall in. So later it became custom to put a little snack on top of it.
