I stayed overnight at a Hilton Hotel to the west of Dublin last week and nipped down to their swimming pool/spa area for half an hour. The guy on the desk told me that I couldn't take a dip unless I wore a hat.
Is this really a hygiene requirement? And, if so, why don't other swimming pools insist on it too? Keen to submerge for a few minutes, I coughed up a couple of euros for the regulation head gear, which was far too tight and very uncomfortable. Talk about taking the pleasure out of swimming.
