That's good information.
If you compare packet traces from the same laptop at the office to that
website, and then at the customer's site, where does it look different?
Considering only a layer-2 link is in between the first thing that comes to
mind is MTU.

Yes, they have different IP's.

Well, I could, however if I bring the same laptop back to my office and
'bypass' the fibre link, give the laptop the same IP as the site on the
other end of the fibre has (after disconnecting the fibre link), it
works fine.
I know that this is due to a problem somewhere between here and the
remote site, but I haven't found out what. I'm quite confident it's not
an IP/routing issue, per the test above, and the fact that this is
literally the one and only HTTP site they have problems with (at least
so far).
Although I can't tell for certain, I keep thinking it has to do with the
retransmission. However, even after reviewing each frame, I'm not
knowledgeable enough at that level as to understand why the retran is
happening, whether the packets are ultimately received (not
knowledgeable enough....yet, that is ;)
