Whomever is responsible for opening the Lobby at 6:00 AM is consistently late. The outside mail box seems to be locked too. My job requires that I drop off the mail when your lobby or outdoor mail box is unlocked. That is not always the case at 6:00 AM


These e-card's are the best! Classy and lovely!
