Tipping
Tipping is appreciated but not mandatory. In restaurants, 10-15% is common for good service. Pubs generally do not expect tips for drinks.
Working there
Hospitality workers are covered by national minimum wage and employment law. Many staff are international, including EU citizens who can work freely. Non-EU workers usually need employment permits, which can be restrictive for entry-level roles.
Rules on pay and visas change. Check official government guidance before you move.
