This one has been a long time coming for the Gripes list. Exactly what makes people think that I want to hear you eating food while you’re speaking to me? At least once a week I answer the phone to someone eating their lunch in my ear. This has to be one of the rudest and disgusting things you can do to a person; it is no different than talking with your mouth full. At this point I just politely ask them to either stop eating while speaking with me or finish their lunch and call me back when they are finished.
Did I mention this is rude? Good.
