Just information for PayPal team. Today i log-in in my PayPal account with Russian language settings and see this message:
Hi <last name>
I would like to inform you, that in Russan languge this greetings sounds very rude and insulting. Hi <first name> is ok, but hi <last name> is rude.
Using only last name without first name in some official conversatio is ok. But in service/customer relationship this is very rude.
Very strange, that so big corporation as PayPal work on Russian speaking market and don't want to know the aspects of local culture.
