"Hi, welcome!"

[Kashflow]

why not "Salut, bine ati venit?

[Jan-Niklas7]

or bine ai venit?

"Servus" should also work for "Hi"... It doesnt say in this case if you know the person or not. If it is someone you know, eg. a buddy from your peer group you say: "Servus!" .

For learners: "servus" is a regional greeting. There are places (e.g. Bucharest) where no one uses it and they might not even know it. Sort of like "howdy".

My wife is from Bucharest and ive never heard anyone in her family say "servus"

"Servus, bun venit!" ... I'm used to say it like this (from other romanians).
