Is OTHER wrong in the post ? POST : We work in an office setting in a small building. Our job duties require us to share some of the computers/workstations - not ideal, but necessary given the specialized software/hardware we use. I occasionally share a workspace with a coworker we'll call Dave. Dave is a nice enough guy. Dave, however, has some serious personal hygiene issues. He smokes like a chimney (and smells like it) and constantly has a "smoker's cough" and sneezes 2-3x per hour. Whenever he sneezes, he sneezes INTO HIS HANDS and will not wash them before then touching shared equipment (keyboard, mouse, etc.) If we have food catered, he will eat over the equipment and then LICK HIS FINGERS before then touching the equipment. There are other examples but I think you get the idea. Again, this is on a daily basis.

I have to share a workstation with this guy and I find this behavior disgusting. I am the only one who has to use this workstation with him. Other coworkers will witness him doing this and make faces or laugh, but because it's not "their workstation", no one cares enough to say something. Management doesn't care unless he were to actually break something, which he hasn't done. I have said something to him to please clean up/stop EVERY SINGLE TIME I see him do this, as I am often seated just feet away and I can watch him working. Despite my revulsion, I began by asking politely. He responded politely at first, as well. However, this behavior has continued for months, and I have become less and less polite each successive time. It has gotten to the point that the issue is starting to affect our working relationship. He now responds sarcastically and acts like I am being an asshole for asking him not to lick his fingers and then touch our shared keyboard. I have taken to carrying Purell wipes over to the workstation and wiping everything down before using it and avoiding contact with him. So, AITA?
