In more words, it can be argued that meeting in parks and restrooms was the "only option" years (and years) ago.

Today almost all gays in the developed world (and 100 percent of your audience here) has access to the Internet, with sites that allow for local hook-ups, actual dating, community groups, etc.

Public bathrooms are still used as a commonplace device in porn movies, a nostalgic carryover for some.  And if you need more, there are gay bars, in some bigger cities, where you can engage in "bathroom theme nights" – for all that implies.

I just remember being in a major city park last summer, washing up after a piss, when two guys starting reciprocating blowjobs in an open stall.  A father walked in, leading his young son by the hand, and turned him around so fast it looked like his wrist would snap.

So at the risk of repeating myself, no.
