Prepare for first world problem complaints:
The UPS delivery people in NYC absolutely HATE trying to do their job (and, as a result, I hate using UPS). While FedEx and UPS will do everything they can to get into your building to drop a package off at your door or near the mailbox and will put notices inside, UPS just puts their notice on the front of the building door like they just rolled by and flung the damn thing at the door.
