And then some brain dead numpty will come and sit on the seat next to you even though there are loads of completely empty seats elsewhere.
Same as they do in cafes, cinemas. Even the beaches aren't safe from such morons. We often walk to a quite part of the beach and then the "group from hell" appears and plonks themselves down right next to us, with their obligatory music, several screeching kids, loud talking, etc., even though there was virtually an entire beach they could have chosen, but no, we have to endure their noise, sand kicked onto us by their out of control kids, etc.
Fair enough on a busy beach, in a full cinema, full car park, busy cafe, etc., but completely brain dead, moronic and selfish when people do it when there are lots of alternatives.
People don't seem to have any respect for "space" of others. One of the good things (the only good thing really) of Covid was everyone having their own space and others not allowed to invade peoples' space.
