As well as the authorities as you rightly say families may well get a little bit angry least to say the hubby!!
If you have a punch up in phill firstly many phills will have access to weapons (most of the families houses have machetes and other clubs around in case burglar bill turned up one night as the police will be in no hurry)
Also if the police do turn up and if a whitey invollved they will be there with the blues and twos on, to give out fines. How do you explain the adultery away???
