Well, I would have my new diffuser today but the mail lady didn't come. They said they had no response and that they left a notice. . . I've searched the entire property for this " notice " My wife was home all day waiting for it, and the only thing we got was from UPS, which was my co2 checker. Our outgoing mail was still in the mailbox. . . Our mail lady sucks. One time she wrote on some of our mail " to slick ". And I didn't get what it meant until I figured out she meant the dirt road was TOO slick. On that day it was damp, not bad at all. She drives a jeep and my wife drives a smaller SUV type car so I know if she can make it with no problem ( she's not a great driver ) the mail girl could have. Laziness. . . Wanting to get off early. . . Wanting to keep the car clean? I dunno. I don't see why she would " leave a notice" and not pick up the out going mail. . . Smells fishy to me. . .
