Even it were compulsory to leave contact details, do staff of such establishments have any way to check the details given are genuine?
Well, pubs are within their rights to check ID to ensure the person visiting is of drinking age[1], and the ID that most people use is a driving licence, which has details on it and it's a criminal offence for them to be wrong unless you've very recently moved house. While you could use other ID e.g. a passport, this does mean they'll be able to usefully check for the vast majority of people.
[1] They don't have to have suspicion that they're not to check, so it's perfectly legal to ID an 80 year old.
