We recently offered up a handy guide to help you get a bartender's attention in a crowded bar. Professional drink slinger "Keith" added his tips to the list.

"I'm a bar back at a local casino and do plenty of bartending as well. Staying out of our blind spot is a GREAT plan of attack to get your drink. Those areas where no one is standing? Use your head, no one is there for a reason.

And if you are ordering more then one drink you had better tip more then a dollar. If it's happy hour, you better tip us more then what you normally would. Common courtesy says tip even if we do a bad job, the lower the tip the worse the job, but don't be a jerk about it. You're not perfect either.

Oh and don't tell us how long you've been waiting, we don't care, we have been working our butt off to make things run as smooth as possible, we don't like being told we're doing bad when we're working the best we can."
