Try these ideas ~ But explain to your regulars whats going on first or you may end up with a totally empty pub!! Put classical music on, change the juke box to jazz, or stop music altogether, don't have live bands, get rid of any pool table or pinball machine and replace it with either a bar billiards table or nothing, sell food, prohibit smoking, insist on all drinks being served in a glass, don't allow high influence drinks such as snakebite to be served, ban smoking and don't show sky sports for free - insist on ticket only viewing. Introduce a loyalty scheme whereby you issue cards (kept behind the bar) with name address and phone number on it (easier for the police should it ever come to that) then every ten stamps is a half price drink. A word of warning - if the situation isn't dealt with you will lose your good regulars as they won't want to drink in a pub that has a reputation for being leary
