lol. You have really no idea. There is no law or regulation that gives them this right. It’s more their own consideration and i believe that goes beyond their authority. Your OPINION may differ but that does not mean that this is a necessity like financial services providers. If i want to see what type of underwear a potential tenant wears before giving him/her a rental contract, i can also ask it. But there is no law that stipulates this and I consider it a breach of privacy. You may not, brave new worlder.
And they dont even check wether it is ‘legitimate’. They dont even ask for tax statements. You are a joke.
