They prefer to go to the disco and get drunk and party on your tab.. But without being hard about it.. If your paying then you control the situation..
Sorry babe.. I want to go now.. You dont need to be a prick about it but its your time if your paying..
Give them and inch and they will take a mile. One disco turns to another and the next thing you know your in Safari, drunk as a skunk and its 7 am with little hope of performing or perhaps even finding your way home
You need to learn the firm but fair approach.. Take no cr@p..
