I've spent many a wasted minute running around my parties in search of the bottle opener. It always gets lost, carried from one room to another, or absent mindedly pocketed by a guest. To ensure that you don't have to ask two thirds of your guests, have you seen the bottle opener?, hang it near the beer. With a hammer, nail a small nail at eye level above the beer cooler in an easy to spot place. Hang one or two bottle openers for guests to use to open their beer as they drink them.
