If the courier in question is 6'2" that might be the case, but I suspect if the person was much smaller and is a heavy sleeper, that it wouldn't be too bad.
I’m 1.97m or so and it’s really not designed for me. I suspect it’s optimised for those at 1.6-1.7m.

I agree with OP, if this was a first class flight, it wouldn't be a bad gig.
