I had an Early Air delivery for a high rise apartment building. I get into the lobby and the system to call a particular apartment is out of order. There is a phone number on the package (an envelope) which is from a company's payroll department (so it's problaby someone's paycheck) I wait about 5 minutes for someone to come in or out, no luck. Against my better judgement, I use my own cell phone to call the number on the package, no answer, I leave a quick message and go on my way, delivery notice left. This town is actually covered by another center, but the center I work out handles the EAM's for this town. I will not be able to return. Within the hour, I start getting a call from the person who was supposed to be receiving this package. I realize I've made a mistake when he starts blowing up my phone. He called 26 times, and starts leaving messages about how he's gonna kick someone's ass if he doesn't get his package. Now I'm definetly not going back. Lesson well learned, don't use your own cell phone for work related purposes.
