--Just a couple finer details to the other follow-up message. Everybody
counts differently, and every different brand of pour spout pours differently.
Generally, a four count (lifting the bottle ON four) is approx. 1 oz. You
also have to realize that 1 "shot" could be either 1, 1 1/4, or 1 1/2 oz.
depending on your local liquor laws. Your bar should have a current copy of
the laws, or they should get one. All in all, you have to test your own
pours. It's takes some time to get it right every time... but eventually
you'll be able to do it with your eyes closed.
