well thats probably because you wear gloves and keep your shoes on while the rest of us are exposed to some of the nastiest bugs in the world(MRSA, VRE, MDRO, and acinetobacter) from less then sanitary conditions.
Since you have thrown your lot in. say i come to the CP with OR style shoe covers that go up to the knee, along with a HEPA duckbill mask with face shield, and chemo gauntlet gloves that go to mid forarm, along with a gown, am i gonna get a secondary or just dirty looks.
You may think its funny but thats the gear that is used in hospitals when staff goes into a patients room that have tested positive for those bugs.
