Why are fewer English people going to their local pubs for a drink? Are they aware that many pubs are shutting down due to lack of customers?

They need to offer either food of a quality you can’t get at home (true gastro-pub experience) or alternative entertainments - live music, poker nights, sports viewing etc.

A range of alcoholic drinks

Why do liberals think it is okay to steal votes while the rest of us obey the law(s)?
