Vayikra bulletin in PDF format

If a chazan  leaves out something essential from his silent shemoneh esrei (e.g, ya’aleh v’yavo), and he did not realize it until he finished, he may rely on the chazaras haShatz to fulfill his obligation.

We learn in the sedra of the week, VaYikra, that HaShem detests a korbon which in actuality is stolen goods. Perhaps that would apply nowadays to davening–if you are disturbing others, not letting them daven properly , you are “stealing” from them their time with HaShem.
