That’s too bad. I feel sorry for you. However, I didn’t see any point that you raise this up to let the restaurant know about it. It’s okay to feel disappointed but for this situation or any situation like this I think you should complain them. So at least they would know they didn’t treat you right and that you deserve an apology.
At first, I told my mom about this that I should notify the manager. But my mother told me that it could be just my point of view. I decided not to inform the restaurant. But later, I asked my siblings for opinions, which they felt the same way as me, but at that time we couldn't do anything. So we decided not to go to this restaurant again and not recommend this restaurant to anyone with a reason instead.

If that happen to me that could make feel very disappointed as the same and think you should complain their restaurant manager instead of their workforce because what you have told to us, it seems that them did not look like feel to apologize to you and the way they act so that the restaurant manager knows what should they do to their staff and you deserve a properly apologized.
