Fucking UPS. Drove in to work on my day off because I needed the $30,000 delivery. My mother-in-law was going for open heart surgery on Moday, I couldn't come in during the next 7 days.
UPS driver, walks up to the door, sticks a missed delivery note on the door and walks the fuck away.
Didn't ring the bell, didn't knock, didn't even wait 10 seconds.
