Anecdotally, I don't think there's any question that people have relaxed on the social distancing with masks. BUT - I also think it was slipping quite significantly before the masks, so that's another part of the equation... is it a cause of it slipping, or has it only accelerated the inevitable? And if it's the latter, then obviously, masks are now PROVEN to mitigate a fairly large proportion of the risk even at < 2m. Passing someone in a shop isn't the same as sharing an office space, the risk of catching it that way was already far lower (even with no measures at all).
