Working in a 1st and 2nd level helpdesk area opposite a kitchenette, we often get people who talk quite loudly right across from us. At times it is very difficult to hear people on the phone or to hear voicemails.
I am looking for some suggested wordings for a sign to ask people not to talk so loudly. We don't want to sound nasty and work is meant to be fun, but we just need people to be mindful of the fact we are often on the phone, trying to help people just like we help them when they call.
Would prefer no "funny" suggestions as it's quite a serious department, but also don't want to sound forceful.
