Had this happen twice in three months at two different restaurants. One was a $10 difference (OK, maybe they misread what I wrote) while on vacation, and Chase credited us the amount. Just dined out and left a $24 tip on Sunday. The charge posted over $30 higher (and didn't even end in the same cents amount), as if we left a 50% tip. Filed another dispute but hoping Chase doesn't take two similar disputes in three months against me. Hopefully, having copies of the receipts and uploading them makes it look like I'm not just taking advantage of someone.
