Pretty much every oil change should be a hot oil change, but I wouldn't doubt that a lot of places don't care and just drain it regardless (like if you drop it off the night before and they just fire it up for 20 seconds to move it into the service bay.) Cold oil doesn't drain as well, so I'd happily pay a little extra to make sure it's done right.
All fluids at 48k does seem excessive, but brake fluid is probably due (likely been over 2 years.) Alignment may or may not be needed (maybe they saw some odd tire wear?), but lots of people like to get an alignment every year or two, regardless. It's not totally outrageous.
Having said all that, if it were my car, I'd just do what was actually required, i.e. the $400 service. Can't really blame them for trying to upsell, but it sounds like they were probably d-bags about it (step daughter in tears). There's no excuse for that.
