I really hope this will never happen to any of your customers in the future

BBQ Un In is one of the restaurants I frequented as it is a nice place with delicious, reasonably priced food. Yesterday I came there and ordered cheese beef rolls with sides, I couldn’t finish it so I took the leftover home. Today I had it for lunch and as I was chewing one of the rolls I heard a loud CRACK as I bit into it, I could feel something very hard and much bigger than a stray sand grain. When I took it out I was a bit terrified to find that it was a tiny shard of glass, and I was able to take out a second piece in that same bite. It was very concerning since I could have swallowed some of it into my belly already. My guess is that they put their glasses too close to their food preparation area and yesterday a glass broke (they were very busy last night) and a shattered piece landed in my beef roll.
Dear BBQ Un In, you are one of my favorite restaurants in Nha Trang, I like you a lot but there are serious improvements you need for your food preparation process. I really hope this will never happen to any of your customers in the future.
