Hungarians are generally very ready to help if you need directions or assistance. The biggest barrier is still the language – in Budapest you can survive on English but elsewhere you’ll need to muster a little German, as well as the polite basics in Hungarian. Never say “thank you” when paying; this is understood in Hungary as “keep the change”. If you want to leave a tip, ten percent will do, and, in restaurants, is expected.
Hungary’s dominant religion is Catholicism but there are many Protestant churches. Respectful clothing is expected in places of worship. Women travellers should not expect any particular hassle in Hungary.
