I know a fair few, and from my experience most are self entitled violent pricks. I know them via working in a bar that a group always frequent when they come up this way. One of them once threatened to shoot me for refusing to give him free drink
Another brought his son in and was playing pool with him and the kid beat him and he punched this 13 year old right in the face and started going mental about disrespect
Obviously all won't be like this (I bloody hope not anyway) but yeah..my personal experience hasnt been too grand
