It's perfectly fine to be nice to one another, and interact, and chat a bit if someone wants to make conversation (as some people get very lonely.) Indeed, some people have stated that their interaction with checkout operators, shop assistants, cashiers, and doctors (and their receptionists,) and the like, is the only human interaction they get.
It is NOT perfectly fine however, to be fucking gasbagging and yabbering on, throughout a FILM that most people have paid probably a tenner to go and see - not including the car parking fees/travel costs, and food they may have bought.
I will complain, and HAVE complained to the ushers when people won't stop talking, (or are rudely scrolling through their damn phone,) and they come in and tell the person to be quiet/switch off their phone...
If you want to yak yak yak yak yak during a film at the cinema, like some entitled, selfish little child, then FUCK. THE. FUCK. OFF! out of the auditorium, because you are spoiling the enjoyment of the film for MANY others who have paid good money to see it (and HEAR it!)
They are the same arsehats who go to the swimming pool, (with their mate) and spend the whole fucking time yabbering at the side of the pool together, hardly doing any swimming, and getting in everyone's way! They are also the same arsehats who talk very loudly in restaurants and cafes, because they like the sound of their own voice, and think everyone should hear them. They are also the same arsehats who do performance parenting! etc etc etc...
In short, attention-seeking pillocks!
