No Bucks/Hens nights was one of my rules as a pub bouncer. It’s always trouble. It’s mostly a group of friends out for a piss up and extremely bad behaviour at the expense of other patrons enjoyment.

Some important context here is that this is an effort to deal with terribly behaving British tourists, since the same bylaw also bans walking around nude or only in underwear. In addition to just being terrible tourists generally, there’s a history of British tourists treating Spanish beaches like their personal vacationing grounds and not a different country where other people live and speak a different language.
