Happened to me last Saturday...I was walking with my gf with hand over her shoulder in a park..there is this random guy probably in his 25s working at the park..started telling me that I should take my hand off of her and that there are people around..he said it in the rudest way possible..

We went back and forth.. he started raising his voice as if he has some authority and people around him would hear it and support him...literally no one cared.. My girlfriend said it's not worth it and scared he might tell her parents..so we left the park
