Stronglifts 5x5 Envy? Not really envy, but...

So does anyone else out there do Stronglifts 5x5 and find themselves counting other peoples reps/sets at the gym to see if their doing 5x5 or something else? I've found myself doing this for the past week or so and have counted like 3 other people doing 5x5, I don't know if they're actually on the stronglifts program or just happen to be doing 5 sets of 5 reps.

Anyway, I just thought it was somewhat funny and a little distracting, what are your thoughts?
