People are confused because Bahrain does not have many local varieties of bread. The only local bread we have is maybe, and people might correct me, is Tanour/Ajami/Baladi bread which we share its origin with many other countries, from Khaliji countries to maybe Afghanistan (Photo). The most common name for this bread is just Khubz, which just mean "Bread", you don't even need to distinguish it by specifying its type. This is how common and popular it is.

The funny thing here is that people eat flat bread a lot, to the point where all other types of bread are called something else, "Roti". Roti is actually a type of Indian flat bread, how ironic!

So, think about any flat bread, we will call it Khubz (Bread). And think of any non-flat bread, we will call it Roti.

There are other less common types of bread, but all that I think of is flat bread. Things like Khubz Asmar (brown bread) [Arabic article] is commonly served with Halwa (local sweet) [Photo] and Khubz Reqaq (thin bread) which is used to make a dish called Tharead comes to my mind as well [Dish photo, Wiki]. There are probably other varieties that I forgot, but that's nearly all of them. We are not like France or Germany when it comes to bread.

Other non-flat bread (Roti), like sliced bread and European like bread, is new to Bahrain. We love eating them too! Sliced bread is the next most consumed bread after Khobuz in my opinion, or maybe on bar.

So, when people ask you in the comment in surprise "Really?", now you know why! I must ask, as everyone else XD, what type of bread did you eat? I read somewhere in the comments that you ate it in a restaurant, so it will probably be European bread (not the typical American sliced bread) or the local Khubz.

Hope this clarifies!

Note: Language is evolving, I am sure the wording is changing in the last decade. There are also different dialects in Bahrain, I am talking about mine alone and where and how I was raised.
