Ewww...
Who'd want to do that publicly? You'd just come across like a thoughtless, desperate perv and borderline (or all-the-way) freak.
When you say "porn" are we talking
Maxim-style cheesecake/pin-up shots of shapely, scantily-clad (but clad) vixens (but nothing else actually going on)...
or are we talking more in the realm of "INTERRACIAL TRIPLE-PENETRATION MEGA HARDCORE CLOSE-UP AMATEURS WITH STRAP-ON MIDGETS!!!" fare?
There is a difference...
If it's the latter, I don't know how someone could sit and watch that kind of stuff with others around, in full view. If nothing else, I fear I'd be marked the "campus creep" or "Captain Jack"
. Who'd want to sit next to me anywhere, or have a conversation if that's how they see me...a guy who is too pervy and hard-up to be a bit more private and discreet in his viewing habits. Speaks volumes about a person, IMO (not "porn-watching", mind you...I'm not talking about that; just the "where" and "when" aspect).
I'm big on the whole "there's a time and place..." thing; and a public computer lab, with others around, probably ain't it. Jeez...
That would kinda piss me off as an lab employee (or volunteer).
