Behind the bar, you need a lot of bar tools and equipment, often more than you think, especially if you want to be perceived as a professional. Most bars will have the essential equipment, such as shakers and bottle openers, but depending on where you work, they may not provide all the things that make your job easier. Aside from the most common items (bottle opener, wine key, shaker), there is a whole list of other tools and things that are useful behind the bar. Now this list is what you as a bartender should bring to work, not the things that should be naturally supplied by the restaurant / bar. The key reason for all of this stuff is that it will make your life easier, and it will help increase your income, believe it or not. A lot of the stuff on this list is there to help your guests have a better experience, and in return, they will reward you with better gratuities.
