In a number of press articles, people who abuse the public transport service by not buying a ticket are normally called "portoghesi" (Portugueses).
What is the origin of that expression? Isn't it offensive against the inhabitants of Portugal who have their own paid public transport service? Or is it that Portugal offers free transport to everyone?
Examples from news:
- Maggiori controlli per stanare i portoghesi del biglietto
- Tentava di fare il portoghese
- L'annoso problema dei portoghesi
