Anyone know of a bakery that sells fresh slim baguettes in the south bay, west la or silverlake area?

thanks in advance!

No it was a miscalculation and no one rechecked our friend's math since she usually tips 20%. It was a mistake, it wasn't deliberate, we apologized and told her it was our mistake. We gave her the 20% tip.

Thanks everyone for the feedback. After hearing everyone's thoughts i agree that it wasn't rude and i understand.
Although, if i were a server, i don't think that is something i would ever do. I would assume it was a mistake and let it go. I commend the waiter and the service that harry nile referenced.

Is it ever ok for a server to ask for a larger tip? I was at a restaurant the other night (pretty nice restaurant if that matters) and my friend miscalculated and only left 10% tip. The server came back with the receipts asking us to make sure it was correct. Although we all felt bad for the miscalculation, we were all taken aback and felt it was a bit rude. What do you guys think?
