On my upcoming visit to Germany this spring, there is a person who I have met on a previous visit and has become a friend. She is a senior citizen and has a handicapped permit. Further, she tells me that so long as I am with her on regional trains or city public transit anywhere in the country that I could go for free.
I am perfectly willing to buy my own fare tickets and do not wish to take advantage of something that would get me a penalty fare and trouble.
Would someone kindly explain this clearly to me?
Thank you in advance for your help.
