Business Hours

Can someone PLEASE help me understand how the average American, one who works a "9-5" gets anything done that requires it to be done during "Normal Business Hours"????? 

I realize that I have had a lot going on between buying a house and having a baby, not to mention the every day life that goes on during these monumental events, but I cannot possibly be the only one who has had these things simultaneously going on.  How do other people do it, "it" being accomplish things such as receiving packages that are only delivered (and require signature) during business hours, or receive services such as; home repairs, deliveries, doctor visits, vet visits, installations etc. all while being at work during those same business hours?  Why does it seem like every time I turn around I need to ask for some amount of time off in order to get X done because it is not even an option to get it done after 5pm or on a weekend?  How is it that people avoid pissing off their employers asking for all this time off?  I can assure them I am not hanging out by a pool when I say I need the afternoon off in order for my carpet guys to come back and reinstall carpet AND fix that damn hole, but I don't think they believe me.  Over the last month and/or over the next month I can think of the following reasons I have needed or will need time off.

-Packages being delivered that require signature (this has happened twice already and I only suspect that it will continue to happen a lot more since people are ordering things off my registry and having it delivered*by request*)
-When above packages have attempted to deliver 3 times all during business hours (duh) I have to make it to the post office to pickup the package.  Their office hours are 8:30am-4:30pm! (actually I just realized that they do provide a 2 hour window for us working class on Saturdays from 10am-noon).
-Best Buy delivery- Fridge
-Best Buy Installation of my theater system (originally they said they didn't have Saturday hours, after I assured them I couldn't be the only one they finally agreed to come out on a Saturday)
-Furniture delivery
-Cable Install
-Idiot Cable guy to come back and bury an outside cable (they INSISTED someone needed to be home for them to bury the OUTSIDE cable OUTSIDE, and that they did NOT have Saturday hours)
-Home Warranty-Counter people
-Home Warranty-Carpet people
-Idiot Carpet people to come back out and try again
-Home Warranty-Door People
-Home Warranty-Cabinet people (DON'T ASK, why a different set of people had to come for each thing I listed...trust me it will piss my off!!!)
-All Doctor appointments which is every 4 weeks right now, eventually will be every 2 weeks
-Daycare shopping
-Pediatrician shopping
-Cat needs to go to the vet (poor thing has allergies really bad)
-Flying home for my shower
-Believe it or not being sick...which happens even more being pregnant and ever worse you can't just pop some DayQuil and drag your ass to work...(in my case I don't pop anything and still have to drag my ass to work)

Ok, although I have only listed the above bulleted points there are at least 2-4 points that will actually require mulitple appointments, occurances, or afternoons in order to receive the services; OB appointments, packages, daycare, pediatrician shopping, and any other home warranty issues/services.  I can understand that the frequency in which I ask for a day or afternoon off to accomplish these things would be frustrating to an employer, however, what am I supposed to do????  Again, I cannot possibly be the ONLY person who bought a house requiring services to be set up, deliveries, or service issues AND has a 9-5 job.  I cannot possibly be the ONLY person who is pregnant AND has a 9-5 job.  Somebody PLEASE tell me how I am supposed to manage these services that are ONLY offered during "normal business hours" AND remain employed?!?!?!?!
