It seems we all have our etiquette pet peeves. At Re-find, the top peeve is when we are trying to exit an elevator, but the boarding passengers push inside, instead of allowing us to disembark.
Even if you are in a hurry, just step aside and let your fellow riders clear the door. The same goes for entering and exiting a building or room. Ironically, coming and going would go a lot faster if we all observed this one little courtesy.
